“…This correlates with the low incidence of LSA noted in young women. 32 We also observed that there were no asso¬ ciated endocrine abnormalities, with the ex¬ ception of one patient with ovarian dysgenesis. In addition, the menstrual cycles were normal and the group as a whole was fertile.…”

“…Firstly described by Pinkus et al [4] in 1956, poromas have been considered as glandular adnexal neoplasms of eccrine lineage. According to Ackerman and Abenoza [1] 4 subtypes exist: the HS, the EP, the DDT, and the PH.…”

Poroma is a rare benign neoplasm that derives from eccrine sweat glands epithelium. Its histological subtypes, with respect to its position within skin layers, are eccrine poroma, hidroacanthoma simplex, poroid hidradenoma, and dermal duct tumor. Poromas commonly exhibit benign clinical behavior as they are usually small and asymptomatic and do not exhibit malignant behavior. Although their histological subtypes share similar histological characteristics, they rarely coexist in the same tumor. In this report we present the case of an unusual poroma in terms of histological and clinical behavior as it was large and presented histological characteristic of both eccrine poroma and poroid hidradenoma. Coexistence of different histologic subtypes in the same tumor indicates simultaneous tumorigenesis, differentiation from one cell type to another, or parallel differentiation from a common progenitor cell. Implications in treatment remain unknown partly due to the rarity of such cases.

“…Hidroacanthoma simplex is closely related to eccrine poroma. The latter is also a tumour of the eccrine sweat gland which forms an almost solid growth sharply demarcated from the surrounding epidermis (Pinkus et al 1956). Hidroacanthoma simplex and eccrine poroma show a similar enzymatic reaction pattern, supporting their origin from eccrine duct.…”
