Eccrine hidrocystomas are benign tumors that arise from sweat glands. They often worsen in hot, humid environments. The lesions are typically larger in summer and smaller in winter. They appear as skin‑colored, dome‑shaped papules in the periorbital area, usually along the lower eyelids.
○ Treatment Cooling the affected area may temporarily reduce its size. Laser therapy is generally ineffective.
Hidrocystomas are cysts of sweat ducts, usually on the eyelids. They are not tumours (a similar-sounding lesion called hidroadenoma is a benign tumour).
It presents as small blue papules filled with clear liquid.
Eccrine hidrocystomas (EHs) are benign tumors, which arise as cystic dilatation of the eccrine sweat duct. The lesions of EH have a chronic course with periodic flares in summer months, associated with exacerbation in sweating. Diagnosis is mainly clinical with histopathology being confirmatory. Dermoscopy is a noninvasive tool, which may confirm diagnosis of EH without subjecting the patient to a biopsy. We report two representative cases of EH, with emphasis on dermoscopic features and which well responded to topical botulinum toxin-like peptide.
