Periductal stromal sarcoma of breast with lipoblast-like cells: A case report with review of literature

The specialized mesenchyme of the breast is the seat of neoplasms with distinct morphology, though with considerable overlap due to the ever increasing number of variants. This article seeks to describe the morphologic features of one such rare neoplasm. A 35-year-old female patient presented with a breast lump that was subsequently excised. Morphological assessment and immunohistochemistry were performed and a diagnosis of periductal stromal sarcoma with lipoblast-like cells (pseudolipoblasts), was made. Being an unusual finding in a rare entity of intermediate grade, it has to be considered, before rendering a diagnosis of a malignant, higher-grade neoplasm.

Persistent müllerian duct syndrome

Persistent Müllerian duct syndrome (PMDS) is a rare form of male pseudohermaphroditism characterized by the presence of the Momicronllerian duct structures in an otherwise phenotypically as well as genotypically normal male. We report a case of 40-year-old cryptorchid male who was clinically diagnosed as seminoma in the undescended abdominal testis. A diagnosis of PMDS was made on histological evaluation subsequent to abdominal orchidectomy.

Extrauterine adenomyoma with uterus like features: A rare entity presenting 17 years post hysterectomy

We report a case of a 47-year-old female (posthysterectomy) with bleeding per vaginum. Imaging studies showed a large abdomino-pelvic mass diagnosed as extrauterine adenomyoma with uterus-like features. This pathological entity is extremely uncommon with only few case reports available in the reported literature. This case is being highlighted for its rarity and to discuss the possible theories for origin of this uncommon condition.

Clear cell adenocarcinoma of the male urethral tract.

We present a rare case of clear cell adenocarcinoma of the male bulbomembranous urethra. Mostly these tumors have been described in the female urethral tract with its possible origin from mullerian remnants, wolffian remnants or paraurethral glands. Histologically, these tumors have typically tubulocystic pattern comprising of hobnailed cells with clear glycogenated cytoplasm along with well-defined cytoplasmic membranes. This case is being presented due to its rarity, aggressive behavior and to discuss, trauma as its possible etiological factor.

Primary neuroendocrine carcinoma of the vagina with coexistent atypical vaginal adenosis: a rare entity.

Primary neuroendocrine carcinoma of the female genital tract is a rare entity with aggressive clinical behavior and a poor prognosis. This kind of malignancy arising in the vagina is extremely rare. We report a case of primary neuroendocrine carcinoma of vagina arising in a setting of atypical vaginal adenosis.

Myoepithelial carcinoma arising in an adenomyoepithelioma of the breast: a case report of a rare entity.

Adenomyoepithelioma of the breast is a rare tumor. Malignant change arising in this lesion is infrequent and only a few cases have been reported. We discuss a case of a 56-year-old female presenting with a firm breast mass, which was interpreted as myoepithelial carcinoma arising in a background of adenomyoepithelioma, based on morphological and immunohistochemical studies. This case is being highlighted for its rarity and distinct morphological spectrum.

Peri-ampullary collision tumor - high grade neuroendocrine carcinoma and signet ring cell carcinoma: A case report and review of literature

We report a case of 50-year-old male with obstructive jaundice diagnosed as peri-ampullary collision tumor comprising of large cell neuroendocrine carcinoma and signet ring cell carcinoma. The association of neuroendocrine (usually carcinoids) and adenocarcinoma is extremely uncommon with only few case reports available in the reported literature.
