To date, only 1 example of cystadenofibroma of the epididymis has been reported in the English literature. Here, we present a second cystadenofibroma originating from the epididymis of a 54-year-old man who presented with painful swelling in the scrotum. The scrotal mass measured 6.3 cm and contained a clear yellow, serous to gelatinous fluid-filled cyst with internal papillae. Microscopically, the mass contained both stromal and epithelial components. The stromal component consisted of spindle cells arranged in small intervening fascicles, forming simple cyst and papillae. The cyst and papillae were lined by cuboidal to columnar and ciliated epithelium. Immunohistochemistry staining showed that the stromal component was positive for estrogen receptor, progesterone receptor, and CD10, which are characteristic of ovarian-type stroma. However, the epithelium lining was positive for keratin cocktail AE1/3&CAM5.2, CD10, PAX8, androgen receptor, and alpha-1 antitrypsin, suggesting a possible Wolffian duct origin.

Primary adrenal angiosarcomas are exceedingly rare with a rapidly progressive clinical course and a poor outcome. Establishing the diagnosis can be challenging, and it is complicated by the fact that there are no characteristic clinical or imaging features that are pathognomonic for angiosarcoma. Histologically, they can overlap with other more commonly encountered adrenal tumors. Herein, we present an otherwise healthy 41-year-old woman diagnosed with a primary adrenal epithelioid angiosarcoma. We aim to expand the knowledge of the sparse literature existing on primary adrenal angiosarcomas to help better understand the diagnostic features, clinical behavior, and management of these rare tumors.

Background: Cutaneous exogenous ochronosis (EO) is frequently graded and staged according to the Dogliotti or Phillips classification system, both in research studies and in clinical practice. There are no data to support the use of these systems in either of these settings. These systems additionally purport that the clinical and histopathological findings of EO are concordant; however, anecdotal evidence suggests otherwise. We aimed to determine the clinical‐histopathological concordance rates in EO and to assess the suitability of the Dogliotti and Phillips classification systems for the grading and staging of EO lesions. Methods: Five cutaneous EO cases diagnosed at our institution were studied. Clinical and histopathological data were obtained by medical record and histopathology slide review. Each case was assigned a clinical and histopathological grade according to both the Dogliotti and Phillips classifications. Clinical‐histopathological concordance rates were determined for each classification. Results: Clinical‐histopathological concordance was seen in 80% and 60% of EO lesions when graded according to the Dogliotti and Phillips classifications, respectively. Conclusions: Cutaneous EO lesions do not consistently show clinical‐histopathological concordance. Although the Dogliotti and Phillips classifications may have clinical utility, they are not suitable to grade EO histopathologically. [ABSTRACT FROM AUTHOR]
