Article Synopsis
- Syringocystadenocarcinoma papilliferum (SCACP) is a rare and aggressive cancer originating from skin appendage glands, often linked to previous skin conditions like syringocystadenoma papilliferum or nevus sebaceus.
- A systematic review analyzed 78 case studies from 1980 to 2024, focusing on clinical features, diagnosis, treatments, and outcomes of SCACP, which commonly affects older adults and presents as ulcerated nodules on the scalp.
- The study emphasizes the importance of surgical treatment, particularly Mohs micrographic surgery, and suggests more research into standardized treatment protocols and targeted therapies to better improve patient outcomes and understanding of its relationships with other skin conditions.

Introduction: Phacomatosis pigmentokeratotica (PPK), an epidermal nevus syndrome, is characterized by the coexistence of nevus spilus and nevus sebaceus. Within the nevus spilus, an extensive range of atypical nevi of different morphologies may manifest. Pigmented lesions may fulfill the ABCDE criteria for melanoma, which may prompt a physician to perform a full-thickness biopsy.

- Autosomal dominant inheritance can manifest in a sex-limited manner, where some genetic conditions affect only females despite males carrying the gene.
- Conditions like Grosshans' white lentiginosis and CELSR1-related lymphedema show this pattern, with affected males remaining asymptomatic but able to transmit the gene.
- Other unique skin conditions, such as cerebriform sebaceous nevus and transient abdominal telangiectasia in newborns, have distinct genetic causes and presentations that are important for accurate diagnosis.
