Background: Eccrine porocarcinoma (EPC) is a rare malignancy of the eccrine sweat glands that is locally aggressive with a high propensity to metastasize. Most cases have been treated by wide local excision (WLE) with 20% local recurrence rate. There have been 20 cases of EPC treated with Mohs micrographic surgery (MMS) in the literature.
Objective: To review the literature regarding the management of this aggressive tumor using MMS.
Methods: A comprehensive literature review was conducted by searching the PubMed database using the keywords Mohs, porocarcinoma, malignant eccrine poroma, and eccrine neoplasms.
Results: Most of the reported cases of EPC were treated by WLE, and only 20 cases were treated with MMS. Of the 20 EPC cases treated with MMS, there was only 1 nodal recurrence and no local recurrence. Other reported treatment modalities include radiation and excision with frozen sections. The authors report the second case of EPC on the temple, and the 21st case successfully treated with MMS.
Conclusion: Eccrine porocarcinoma is a rare neoplasm with potentially aggressive clinical behavior. In cases where tissue conservation is important, MMS should be considered.

Background: Eccrine porocarcinoma (EPC) is a rare cutaneous neoplasm, commonly arising from its benign counterpart, eccrine poroma (EP), but potential unrevealed clinicopathological differences between them are not well understood.
Objectives: This study aimed to identify clinicopathological features of EP and EPC and describe the factors that may be associated with the malignant transformation of EP by comparing the two groups.
Methods: A total of 37 cases of EP and 22 cases of EPC diagnosed between January 2017 and June 2023 were retrospectively reviewed, and the clinical and histopathological characteristics were compared using statistical methods.

A 70-year-old African American female with a history of stage IV mycosis fungoides in remission presented with a gradually enlarging, red, ulcerated nodule on her right dorsal hand. The lesion was biopsied, and it showed intraepidermal proliferation with cytologic atypia and increased vasculature in the papillary dermis. Immunohistochemical staining indicated a yes-associated protein 1 (YAP1) rearrangement, confirmed by RNA sequencing, revealing a YAP1::MAML2 (mastermind-like transcriptional coactivator 2) fusion.
