Histopathology: -Some loose aggregates and a few dispersed, fine to densely granular melanin-pigmented polygonal to wavy spindle melanocytes and dendritic cells, seen in the superficial cervical stroma, just below and around endocervical epithelium. – The endocervical epithelium does not show melanocytes or melanin pigment accumulation. – Atypical features and necrosis are not seen. Note: The…
Histopathology: Variable size irregular, haphazardly arranged glands look like an infiltrative pattern, in the wall of fallopian tube, around the central lumen. Some of these glands do not communicate directly with the central lumen, while few communicate with the main lumen (blue arrow). Some glands are small and tubular, while others are large and cystically…
Histopathology: Uterine mass shows the mixture of mature adipocytes and long intersecting bundles of bland, spindle-shaped smooth muscle cells. Focal hyalinised stroma is also seen. Cytologic atypia is not seen in spindle cells and adipose tissue components. Practical points of Pathoclinics: Uterine lipoleiomyoma is an uncommon but easily recognized variant of leiomyoma, occurring primarily in…
Endocervical tunnel clusters Histopathology: Well-demarcated lobulated closely packed variable size cystically dilated glands, just below the surface endocervical mucosa Glands are lined by a flattened epithelium with bland nuclear features and basally located nuclei. Cystically dilated glands contain thick mucinous secretion Here, the overall low-power look resembles that of colloid goiter. Few large Nabothian cysts…
Case History: A some around 35-year-old female patient, hysterectomy specimen received. Sections from cervix tissue show this type of morphology. No gross pathology seen. Mesonephric Hyperplasia and Remnants Histopathology: Few mesonephric tubules and ducts are lined by cuboidal epithelium with bland nuclei. Some tubules and ducts are also lined by flattened epithelium. Occasional tubules contain…
Intestinal adenocarcinoma arising within a mature cystic teratoma Histopathology: Areas of skin and sebaceous glands and adipose tissue. Predominant areas of irregular crowded moderately differentiated glands in an infiltrative manner in a desmoplastic stroma. Glandular and tubular structures are lined by columnar cells with nuclear hyperchromasia, elongation, stratification, abnormal mitoses and clear cytoplasm. Some glands…
