Poroid hidradenoma has both features of hidradenoma and poroma. The histological hidradenoma framework consisting of solid and cystic components, and the presence of poroid and cuticular cells resembling a poroid neoplasm. Despite transforming into malignant neoplasm only in < 1% of cases, its histological characteristics may resemble those of malignant neoplasms. Although the risk of malignant transformation is very low, surgical excision is recommended to prevent growth and/or recurrence. To date, very few cases of poroid hidradenoma have been reported in the literature. Herein, we present a case of poroid hidradenoma on the scalp of a 74-year-old woman.

Article Synopsis
- Poroid hidradenomas are rare tumors that develop from eccrine sweat glands and typically present as nodules made up of cuticular and poroid cells.
- They are classified under poroid neoplasms, which also includes other similar tumors like hidroacanthoma simplex and eccrine poroma, and their diagnosis can be complicated due to similarities with other tumors.
- A case study of a 56-year-old woman with a nodular lesion on her finger confirmed a poroid hidradenoma through histopathological analysis, emphasizing the necessity for careful clinical evaluation and diagnosis for these uncommon dermatological issues.

NUT Expression Is of Diagnostic Utility in the Distinction of Digital Papillary Carcinoma From Poroid Hidradenoma.

Article Synopsis
- There is a challenging distinction between digital papillary adenocarcinoma (DPAC) and benign skin tumors like poroid hidradenoma, as they share similar clinical and histological features.
- Recent findings indicate that poroid hidradenoma often has YAP1-NUTM1 gene fusions, leading to NUT protein expression that can be detected via immunohistochemistry.
- In a study comparing DPAC and poroid hidradenoma, strong NUT-1 expression was found in three out of four poroid hidradenoma cases, while it was absent in all DPAC cases, suggesting NUT-1 testing could aid in differentiating these conditions.
