Touch preparation of high-grade mullerian serous carcinoma presenting as a large abdominal mass, performed at the time of frozen section. Although not always additive, touch preparations can be a useful adjunct to evaluate tumor morphology intraoperatively #pathsky #medsky #pathology #gynpath

Endocervical adenocarcinoma in situ (AIS). While HPV16 is the most frequent subtype detected in AIS, it shows a stronger association with HPV18 relative to high grade squamous lesions. #pathsky #medsky #pathology #gynpath

Endometrial clear cell carcinoma exhibits architecture that ranges from papillary to tubulocystic to solid nests. Unlike its cervical counterpart, CCC of the uterine corpus shows no association with in utero exposure to diethylstilbestrol (DES) #pathsky #medsky #pathology #oncology

Sarcina Ventriculi present on gastric biopsy. This gram positive bacteria is notable for its construction in tetrads and its association with delayed gastric emptying, which may be rarely complicated by emphysematous gastritis and gastric perforation. #pathsky #medsky #pathology

Mast cells with atypical spindled morphology forming aggregates within the bone marrow, diagnostic of mastocytosis. In this case, there is coexistent chronic myelomonocytic leukemia (systemic mastocytosis with an associated hematological neoplasm) #pathsky #medsky #pathology
