Why do syringomas keep increasing in number as they grow?
Syringoma, also known as tubular sweat gland adenoma, sudoriferous cystadenoma, or sudoriferous abscess, is a type of adenoma characterized by differentiation of the distal ducts of small sweat glands, forming a benign skin tumor. The exact cause is not clear, but it may be related to genetics. If syringomas become more numerous and grow larger, it may be necessary to consider an association with endocrine dysfunction. Syringomas can occur at any age, but are most common in young women, often worsening during puberty and frequently having a family history. The lesions are particularly prone to appear around the eyelids, especially the lower eyelids. These lesions are dense, flat papules, ranging from several to dozens or even hundreds in number. Typically, the lesions increase in size during the sweaty summer months and shrink during the colder winter months, generally presenting without significant symptoms.
