Basal cell carcinomas (BCC) are driven primarily by cumulative ultraviolet (UV) radiation exposure resulting in activation of the Hedgehog (Hh) signaling pathway, often as a result of UV-mediated Patched-1 (PTCH1) gene inactivation. Accordingly, BCCs most commonly arise at sun-exposed sites such as the head and neck. Very rarely, BCCs can arise at sun-protected sites such as the genital skin and perianal area.

Cystic Basal Cell Carcinoma with a Giant Vulvar Cyst.

Acta Dermatovenerol Croat

November 2024

Takayuki Suyama, MD, PhD, Department of Dermatology, Dokkyo Medical University Saitama Medical Center, 2-1-50 Minami-koshigaya, Koshigaya, Saitama, 343-8555, Japan; ORCID ID: 0000-0002-6986-411X.

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.

Context: Hepatocyte nuclear factor (HNF)-4α is a marker of gastrointestinal tumor differentiation; however, its expression in endocervical tumors remains unclear.

Objective: We aimed to assess the utility of HNF4α expression as a marker for endocervical adenocarcinomas (ECAs) and adenocarcinoma in situs (AISs), and to establish a minimal panel for distinguishing them from nonneoplastic endocervical glandular lesions and metastases.

Design: HNF4α expression was analyzed immunohistochemically (positive, H-score ≥10) in 323 tissue samples: 57 endocervical neoplasms including 35 glandular neoplasms and 22 squamous neoplasms, 144 nonneoplastic endocervical lesions, and 122 tumors from other organs.

: Cervical mesonephric adenocarcinomas (MNACs) are among the rarest neoplasms of the female genital tract. Unlike the majority of cervical cancers, which are predominantly squamous in origin and strongly associated with HPV seropositivity, MNACs are distinct in both histology and pathophysiology. Despite their unique characteristics, MNACs have historically been managed in parallel with squamous cell carcinomas, resulting in a lack of optimised, evidence-based treatment protocols.
