Abstract :
Eyelid tumors are the most common neoplasm in routine ophthalmology practice and encompass a wide
variety of benign and malignant tumors, predominant being benign tumors. Hidrocystomas are rare, benign,
cystic lesions of the skin often found on the head and neck region and typically occurs on the face in
adults between 30 and 70 years of age. They are further divided into two groups - apocrine and eccrine
hidrocystoma; both closely mimic clinically and morphologically related cystic sweat gland tumors. We
present a “classic” case of eccrine hidrocystoma in a 60 year old female. The cysts are small, clear to blue
and size ranging 1 to 6 mm in diameter. Histologically, the cysts are simple and lined by a 2 - 3 wall layers
of cuboidal epithelium (non keratinizing), devoid of a myoepithelial layer. Eccrine lobules are often closely
apposed, and occasionally the ducts enter the cysts. Immunohistochemically, they stain positive for S100
protein. Management of hidrocystomas mainly involves simple needle puncture with excision en mass.
However, other treatment modalities are also available.
