Background: Acrospiromas are histologically distinct cutaneous tumours of sweat duct origin and usually measure 1 to 2 cm in size.
Objective: We describe a patient with a large benign eccrine acrospiroma.
Methods: Case report and literature review.
Results: A 50-year-old woman underwent excision of a 5.5×5.0 cm cystic mass located on the left gluteal region, and the resulting defect was closed by a local flap. A diagnosis of benign eccrine acrospiroma was made after histopathological examination. On histological examination, the lesion was characterized by multilobular dermal masses composed of a biphasic cell population. There was no recurrence five months after the operation.
Conclusion: Although eccrine acrospiromas are usually benign, they can, on rare occasions, undergo malignant transformation. In addition, the clinical appearance of this lesion is not specific and differential diagnosis from other lesions, both benign and malignant, can only be done after the complete removal of the lesion.
Introduction: Syringocystadenocarcinoma papilliferum is an extremely rare malignant adnexal tumor that typically arises from a papilliferous syringocystadenoma (World Health Organization classification of skin tumors, 2018.). This tumor predominantly occurs in the cephalic region.
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.

Benign cutaneous apocrine sweat gland adenomas in the nose are rare. We present the novel case of a nasal ala cutaneous sweat gland lesion. A 43-year-old male presents with a one year history of a right nostril mass with intermittent clear discharge, triggered by periods of hot weather and increased humidity.
