Tired of Hedging in Your Pathology Reports? Here's What to Do About It

Tips for Submission  ·  All species

If you have ever received a pathology report that reads "consistent with," "suggestive of," or "cannot exclude" and wondered why the pathologist could not simply give you a straight answer, this post is for you. Hedging language in a pathology report is not evasion. It is an honest reflection of what the tissue can and cannot tell the pathologist with the information available. The most reliable way to get a more definitive report is to give the pathologist more to work with — and most of that information is already in your hands before the biopsy is ever taken.

Why pathology reports hedge

Histopathology is pattern recognition applied to tissue. The pathologist looks at a section and identifies a pattern — granulomatous inflammation, a spindle cell proliferation, an epithelial neoplasm with infiltrative growth — and then assigns that pattern to the most probable diagnosis given everything they know about the patient. The tissue provides the pattern. The clinical context determines which diagnosis from that pattern is most likely.

When the clinical context is absent or incomplete, the pathologist is left with a pattern that fits multiple diagnoses with no basis for ranking them. A lichenoid interface dermatitis in the skin of a dog is consistent with lupus erythematosus, a drug reaction, or dermatomyositis — but the histology alone cannot distinguish between them. A round cell infiltrate in the liver could be lymphoma, extramedullary hematopoiesis, or a reactive process. A proliferative lesion on the gingiva could be a peripheral odontogenic fibroma, an acanthomatous ameloblastoma, or a poorly differentiated carcinoma. In each case, the tissue shows a pattern. The clinical information determines the diagnosis.

The hedging language in the report is the pathologist communicating that the tissue is consistent with a diagnosis but that the clinical picture is needed to confirm it. It is an invitation for a conversation, not a final answer. And in most cases, the clinician already has the information that would complete it.

Clinical and gross photographs

A photograph of the lesion before biopsy is one of the single most useful things a clinician can provide with a dermatology, oral, or soft tissue submission — and one of the most consistently omitted. The pathologist examining a 4 mm punch biopsy core cannot see whether the lesion is erythematous or hyperpigmented, whether it is solitary or multifocal, whether it is symmetric or asymmetric, whether an oral mass is sessile or pedunculated, or how large the lesion is relative to the surrounding tissue. These gross features are diagnostically meaningful and the tissue section alone cannot convey them.

For skin cases: photograph the primary lesion in its unmanipulated state before biopsy. An intact pustule, vesicle, or plaque tells a very different story than the same site after secondary changes have developed or after the patient has been treated. Photograph the distribution across the patient. Include scale. If the lesion has evolved, an earlier photograph is often more diagnostically useful than a current one.

For oral and soft tissue cases: photograph the lesion in the context of surrounding structures before any surgical manipulation. Note the relationship to adjacent teeth, the firmness on palpation, whether the lesion is attached by a stalk or broadly based. For masses anywhere in the body, a photograph that shows the gross character and size — before fixation distorts the tissue — can meaningfully influence how the pathologist interprets the histologic findings.

Imaging findings: radiographs, CT, and ultrasound

Imaging data is diagnostic data. It is not supplementary background information — it is part of the clinical picture that the pathologist uses to interpret the tissue. When imaging findings are included in the submission history, they become part of the diagnostic reasoning. When they are absent, the pathologist is interpreting the tissue without architectural context that may be critical.

For oral and bone lesions: dental radiographs and CT findings are essential. A gingival mass with radiographic evidence of osteolysis is a fundamentally different diagnostic problem than one with no bone involvement, even if the H&E morphology appears similar. Knowing that cortical bone was intact on imaging does not exclude microscopic invasion — but it shapes the differential and informs how the pathologist words the report in terms that are meaningful for surgical planning.

For abdominal masses: ultrasound findings — echotexture, vascularity, lymph node appearance, evidence of cavitation — provide architectural information that the biopsy core cannot. A splenic mass with ultrasound features suggesting cavitation carries a different differential than a homogeneous solid lesion. A hepatic mass with portal lymphadenopathy suggests staging considerations that change the clinical question the pathology report needs to answer.

For skin and subcutaneous masses: CT findings indicating depth of invasion, fascial plane involvement, or regional lymph node enlargement place the histologic findings in a context that changes their clinical significance. A subcutaneous spindle cell tumor with CT evidence of deep fascial involvement is not the same surgical problem as a superficial nodule, even when the H&E is identical.

Include imaging findings in the submission history, or attach a radiology report summary. Note what was seen — and what was not. "No bone loss visible on dental radiographs" is useful information. "CT showed a 4 cm splenic mass with evidence of capsular disruption and free peritoneal fluid" is critical information. Both belong in the submission.

Prior treatments and response

Treatment history is not background noise. It is diagnostic signal that changes what the pathologist sees in the tissue and how it should be interpreted. Tissue that has been exposed to glucocorticoids looks different from untreated tissue — inflammatory infiltrates may be suppressed, mast cells may be partially degranulated, and epidermal changes may reflect treatment effect rather than primary disease. A lesion treated with antifungals before biopsy may show partial resolution of organisms. A mass that received an intralesional injection may show focal necrosis at the injection site. Without knowing what was given, the pathologist may misinterpret treatment effect as primary pathology.

Include all systemic medications with doses and duration. Include topical treatments applied to the biopsy site. Note whether the patient was on medication at the time of biopsy. And include the response: did the lesion improve with treatment? Did it relapse when medication was stopped? Did it fail to respond at all? A condition that improved dramatically on glucocorticoids and relapsed on withdrawal tells the pathologist something about the likely immunologic mechanism before the slide is ever examined. A mass that grew rapidly despite treatment is a different clinical problem than one that has been stable for two years.

Bloodwork and other diagnostic results

Relevant laboratory findings are more useful to the pathologist than their omission from submission forms suggests. Systemic disease frequently has histologic correlates that are only interpretable in the context of laboratory data. Hypoalbuminemia in a dog with a chronic skin condition raises protein-losing enteropathy or hepatic disease as contributors. Eosinophilia on a CBC in a cat with miliary dermatitis shifts the differential toward hypersensitivity. An elevated calcium in a dog with a jaw mass raises a paraneoplastic process. Elevated globulins in a dog with gingival proliferation raise plasmacytic and immune-mediated conditions.

A full laboratory printout is not necessary. A brief summary of relevant findings — or the explicit statement that bloodwork was unremarkable — is sufficient and genuinely useful. Culture and sensitivity results, prior cytology findings, allergy testing results, and any other diagnostic data obtained in the workup of the same problem should be included when available. Each piece of data narrows the differential and allows the pathologist to render a more specific, more useful diagnosis.

The differential diagnosis: your clinical impression is part of the answer

The clinical differential diagnosis field on a submission form is consistently underutilized. Many submissions arrive with "r/o neoplasia," a single diagnosis, or nothing at all. All of these miss the opportunity to communicate clinical reasoning that genuinely changes how the pathologist approaches the case.

The purpose of a differential is not to demonstrate diagnostic confidence or to constrain the pathologist toward a predetermined answer. It is to share the clinical reasoning that produced the decision to biopsy. What did the lesion look like? What clinical features pointed toward specific diagnoses? What are you most hoping to rule out, and why? Even uncertainty is useful. "I think this is most likely a mast cell tumor based on cytology but I'm concerned about the rapid growth and the location near the prepuce" tells the pathologist that cytology was performed, that the clinical impression leans toward MCT, and that location and growth rate are elevating concern. That context shapes which features of the tissue receive the most attention and how the prognostic language in the report is calibrated.

An uncertain differential is more useful than a blank field. "Top differentials: pemphigus foliaceus vs. drug reaction given recent medication change" focuses the pathologist on acantholytic layer, inflammatory infiltrate character, and the timeline of lesion onset relative to drug initiation. "Skin mass, unknown" provides none of that. The pathologist and the clinician are partners in the diagnostic process. The differential diagnosis field is where that partnership begins.

A practical note on submitting supporting materials

One barrier that prevents clinicians from including clinical photographs, radiographs, and other supporting materials is logistical: many diagnostic submission systems have no straightforward way to attach these files, and materials sent separately by email or uploaded to a different portal frequently become disconnected from the case by the time it reaches the pathologist. The intention to provide complete information is there; the mechanism is not.

Vetopathy's submission portal includes a document upload feature that allows clinical photographs, radiographs, CT images, and other supporting files to be attached directly to the case at the time of submission. These materials arrive with the case and remain linked to it through the diagnostic process. If you have been omitting photographs or imaging from submissions because there was no obvious place to include them, that is no longer the constraint it may have been with other services. The portal accepts standard image formats and PDF reports, and uploaded files are reviewed by the pathologist as part of the case workup — not filed separately or overlooked.

What changes when you provide complete information

The practical impact of complete submissions is not theoretical. When the pathologist has clinical photographs, imaging findings, treatment history, relevant laboratory data, and a clinical differential, the report that results is fundamentally different from one produced from tissue alone. Hedging language narrows or disappears because the clinical context allows the pathologist to rank the differential and commit to the most probable diagnosis. Comments become more clinically specific because the pathologist understands what the clinician is actually trying to decide. Recommendations for ancillary testing become more targeted because the diagnostic question is clearly framed.

The inverse is also true. A tissue submission without context produces a descriptive report — here is what the tissue shows — rather than a diagnostic one — here is what this means for this patient. Descriptive reports are not wrong. They are incomplete. And the information needed to complete them is almost always already available at the time of submission.

Quick reference: what to include with every submission

Information Why it matters
Clinical photographs Gross appearance, lesion distribution, and size that the biopsy core cannot convey
Imaging findings Architectural context: bone involvement, depth, lymph node status, cavitation
Lesion history Duration, rate of change, prior episodes — behavior over time narrows the differential
All medications Drug, dose, duration — treatment effect can mimic or mask pathology
Treatment response Improvement, relapse, or failure to respond — immunologic and biologic clues
Prior biopsies or cytology Previous diagnoses from the same lesion or site if available
Relevant bloodwork CBC, chemistry, culture results — systemic context for tissue findings
Clinical differential Your top 2–3 diagnoses and what clinical features support or argue against each
Primary clinical concern What you most want to rule out — even if uncertain, this shapes the report

The pathology report is a product of two inputs: the tissue and the context. The pathologist controls the tissue analysis. The clinician controls the context. The more complete that context, the more complete — and the more definitive — the report.
