The eccrine poroma is an uncommon benign neoplasm previously thought to originate solely from the eccrine sweat gland. Initially believed to present on hairless acral surfaces, a more extensive distribution has been described. We report a case of a 55-year-old man with a slowly growing, 6-cm eccrine poroma on the medial aspect of his right foot of 40 years' duration. Clinicians should be aware that poromas can be of either eccrine or apocrine origin and can occur in areas other than acral skin. They also should understand the subclassification of the poroma family of neoplasms.

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.

Poroma is a relatively rare benign adnexal neoplastic lesion that usually affects elderly patients in the extremities, with an unclear pathogenesis. It is notable for having a variety of morphological appearances that make diagnosis challenging, particularly when observed on an uncommon anatomical site. Here, we present a case of a woman in her mid-50s who presented with a skin pedunculated lesion over the right thigh.

Article Synopsis
- Poromas are benign skin tumors originating from sweat glands, often appearing as pink or red bumps primarily on hairless areas like palms and soles.
- A 70-year-old woman had a poroma on her abdomen that showed some histological features similar to another neoplasm, syringocystadenoma papilliferum (SCAP), but lacked certain defining characteristics of SCAP.
- This case, showing rare SCAP-like features within a poroma, emphasizes the need for careful diagnosis as it may simply reflect a variation of poromas, rather than representing two different tumors.

Eccrine poroma is a non-cancerous tumor that arises from the intraepidermal portion of the eccrine sweat glands. It usually appears as a solitary lesion on an extremity, commonly on the foot or sole, and is often subject to delayed or inaccurate diagnosis in clinical settings. This article describes a rare case of eccrine poroma located on the palm.
