Abstract
BACKGROUND Eyelid tumors belong to a diverse group of neoplasms ranging from benign lesions to malignant tumors. Poromas are common, benign, mostly unpigmented tumors of the epidermal sweat duct unit, that usually grow slowly and occur in elderly people on the palms and soles. In most poroma cases some gene fusions were detected, which were caused by chromosomal aberrations. CASE REPORT We report the atypical case of a 30-year-old female patient suffering for more than 15 years from a solitary, polypoid, pigmented formation with a focal tuberous surface on the left lower eyelid. The lesion was not growing during the first years, but in the last 6 months before diagnosis its size more than doubled, finally reaching 12×14 mm. It was removed and histopathological analysis confirmed the diagnosis of a rare tumor - a poroma. There were no complications during healing and no recurrence was reported. CONCLUSIONS There have so far been only 9 reports of eyelid poromas, and the presented case significantly differed from the previous ones, as it appeared at an early age and showed rapid growth during a short time due to the war-related acute psychological stress. Moreover, it had unusual pigmentation and unpleasant smell. Reporting such untypical cases is clinically important because it is crucial to be aware of the diversity of eccrine poroma manifestation to distinguish it from malignant lesions.
