Background: Cribriform carcinoma is the histopathologic variant of cutaneous apocrine carcinoma characterized by interconnected solid aggregations of neoplastic cells that are punctuated by small round spaces.
Objective: To describe the histopathologic and immunohistochemical characteristics of this under-recognized cutaneous adnexal neoplasm.
Methods: Twenty-six cases of primary cutaneous cribriform apocrine carcinoma were clinically, histopathologically, and immunohistochemically studied.
Results: Seven neoplasms arose in males and 19 in females. The median age of the patients was 47.8 years. The lower and upper limbs were the most frequent sites. Histopathologically, the neoplasms consisted of well-circumscribed dermal nodules composed of multiple, interconnected, solid aggregations of basophilic epithelial cells that were punctuated by small round spaces. Immunohistochemically, the neoplastic cells expressed immunoreactivity for MNF116, AE1/AE3, Cam 5.2, cytokeratin 7, carcinoembryonic antigen, and epithelial membrane antigen.
Limitations: All specimens came from dermatopathology laboratories, and some inherent selection bias may exist.
Conclusions: Primary cutaneous cribriform apocrine carcinoma is a distinctive but little-known variant of cutaneous apocrine carcinoma.

The mammary epithelium has an inner luminal layer that contains estrogen receptor (ER)-positive hormone-sensing cells and ER-negative alveolar/secretory cells, and an outer basal layer that contains myoepithelial/stem cells. Most human tumours resemble either hormone-sensing cells or alveolar/secretory cells. The most widely used molecular classification, the Intrinsic classification, assigns hormone-sensing tumours to Luminal A/B and human epidermal growth factor 2-enriched (HER2E)/molecular apocrine (MA)/luminal androgen receptor (LAR)-positive classes, and alveolar/secretory tumours to the Basal-like class.

Background: Salivary duct carcinoma (SDC) is a highly aggressive salivary gland malignancy with poor prognosis. The aim was to investigate the prognostic factors and survival outcomes in a cohort of SDC patients.
Materials And Methods: This study retrospectively analyzed the clinicopathological data of 61 SDC patients treated at the First Medical Center of the PLA General Hospital between January 2010 and December 2020.

Backgroud: Salivary duct carcinoma (SDC) is a rare and aggressive malignancy with a generally dismal prognosis and no standard of care established, despite a known association with epidermal growth factor receptor 2 (HER2) and androgen receptor (AR) over-expression.
Case: We report the case of a 64-year-old female with extra- and intracranial metastases of SDC with evidence of AR and HER2 overexpression. After progression on first line chemotherapy, was administered neratinib, a pan-Erb2 receptor tyrosine kinase inhibitor.

Cystic basal cell carcinoma (BCC) is a rare subtype of BCC (1). Histologically, it is usually characterized by multiple small cysts without a clinical cystic appearance (2). Herein, we report an unusual case of cystic BCC with a large vulvar cyst.

Introduction: While male breast carcinoma is a relatively uncommon occurrence, its incidence is on the rise, potentially attributed to sporadic pathophysiological mechanisms, primarily involving hormonal imbalances. Invasive apocrine carcinoma represents a small fraction of global breast malignancies, with limited instances reported among male patients in the literature. The clinical presentation of an apocrine breast carcinoma closely resembles that of other breast cancer subtypes, as it is most often described as a solitary ulcerative nodular lesion occupying a retro-areolar region of the breast.
