Dermatopathology
A Diagnostic Lab Built by Dermatopathologists
Sagis was founded on dermatopathology, and it remains the core of everything we do. As a 100% dermpath-owned national diagnostics lab, we bring a level of focus and accountability that corporate-owned laboratories simply cannot match.
About Dermatopathology
What is dermatopathology?
Dermatopathology combines dermatology and pathology to diagnose diseases of the skin, hair, and nails. It requires specialized training beyond general pathology, since skin conditions often present with subtle or overlapping features that general pathologists aren’t trained to distinguish.
Using biopsy tissue, dermatopathologists examine cellular structures under the microscope to identify patterns specific to inflammatory, infectious, and neoplastic skin conditions. This includes melanocytic lesions, cutaneous lymphomas, and other complex cases that require subspecialty expertise to interpret correctly. The result is an accurate diagnosis that gives referring physicians the clinical confidence to guide treatment decisions for skin cancer and other cutaneous conditions.
About Diagnosis
What conditions does Sagis diagnose through dermatopathology?
Our dermatopathologists evaluate the full breadth of skin, hair, nail, and soft tissue disease, including melanoma and non-melanoma skin cancers, complex inflammatory and autoimmune conditions, melanocytic lesions, cutaneous lymphoma and leukemia, and rare malignant neoplasms such as sarcoma. These diagnoses often hinge on distinctions that require dermpath-specific training to catch, such as differentiating a benign nevus from early melanoma or identifying subtle markers separating an inflammatory mimic from true cutaneous lymphoma.
For difficult or diagnostically ambiguous cases, our team reviews collaboratively before issuing a final report, supported by digital pathology tools that enable high-resolution image review and real-time consultation among our physicians. Referring physicians get the benefit of multiple subspecialty-trained perspectives on complex cases, not a single read.
Clear & Concise
A Collaborative Diagnostic Team Behind Every Case
Accurate dermatopathology requires more than advanced technology. It requires experienced pathologists who actively share knowledge and challenge one another to get it right.
At Sagis, our dermatopathology team collaborates on difficult cases as a matter of practice, not as a last resort. When a specimen presents diagnostic complexity, our pathologists confer directly to reach a consensus. The result is a clear, concise report you can act on with confidence.

We also make ourselves available for one-on-one consultations and second opinions, because your clinical perspective is an essential part of the diagnostic picture. That kind of physician-to-physician partnership is what sets Sagis apart from larger reference labs.
Custom Reporting
Trusted Results, When You Need Them
Every report is available instantly through seamless EMR integration or secure web portal, so you and your staff can access results the moment they are finalized. No waiting on faxes, no chasing down paperwork.
Through EMR integration, we can access clinical photos, notes, and patient history, providing valuable context that enhances collaboration between clinicians and dermatopathologists. SEAM further simplifies the workflow by reducing manual entry while keeping results clear, accessible, and HIPAA compliant.
Our pathology services combine speed with accuracy, backed by CAP accreditation and a quality assurance process built into every step, from specimen receipt through final diagnosis. For standard dermatopathology cases, Sagis delivers results in as few as 24 to 48 hours. Cases requiring immunohistochemical studies are typically completed within 48 to 72 hours.

Reporting
Every diagnosis Sagis delivers is backed by a reporting process built for clarity and speed.
Physicians have direct portal access to view results as soon as they’re finalized, with a notation feature that makes it easy to flag questions or follow up on specific findings. For complex or unusual cases, our team is available for one-on-one consults and second opinions, so you’re never reading a report in isolation.
How will I receive biopsy results?
Sagis can work with all EMRs for electronic reporting. Results can also be delivered through our secure online portal, which provides immediate access to finalized reports. Critical or unexpected findings are communicated directly and promptly
Can I consult directly with a dermatopathologist about a case?
Absolutely. Direct access to our dermatopathologists is one of the things that sets Sagis apart. We are readily available for one-on-one consultations, whether you have a question before submitting a specimen or need to discuss a finalized report.
Does Sagis offer second opinions on dermatopathology cases?
Yes. We provide second-opinion consultations on outside cases, including challenging melanocytic lesions, inflammatory conditions, and rare neoplasms. If you have a case that warrants another look, we welcome the opportunity to review it.
Global Result & Slide: From Slide to Diagnosis
Sagis manages the full diagnostic process from start to finish, combining two components into one seamless service.
TC (Technical Component)
The Technical Component covers slide preparation, including grossing, embedding, sectioning, and staining. Our lab follows CAP-accredited protocols at every step, so each slide meets the quality standard your diagnosis depends on.
PC (Professional Component)
The Professional Component is the diagnostic interpretation itself. A board-certified dermatopathologist examines the prepared slide and delivers a definitive diagnosis, supported by peer consultation when a case calls for it.
Global Result
When TC and PC are combined, physicians get a single, streamlined result: from slide prep to final diagnosis, handled entirely in-house. No coordinating between separate labs or vendors. Just one accurate report, delivered efficiently.
Other Arrangements Available
Every practice has different needs, and Sagis offers flexible support to match.
Dermpath Vacation Coverage
When your in-house dermatopathologist is on leave, patient care shouldn’t pause. Sagis provides seamless, short-term coverage so your practice keeps running without interruption or delay in turnaround time.
Overflow Dermpath Business
