Cylindroma

Cylindroma is a rare, slow-growing, benign tumour of the skin. It mostly affects the face, scalp, and neck regions.

Types include:


 * Dermal eccrine cylindroma, a benign tumour of the skin
 * Adenoid cystic carcinoma, a malignant tumour of the salivary gland

Signs and symptoms
The tumours are smooth, firm, pink to crimson in hue, commonly pedunculated, and often numerous. Tumours can sometimes cause pain. The scalp and surrounding skin are the most common sites. When pedunculated, the tumours may be nearly hairless, although the smaller lesions produce dermal nodules with minimal hair loss over them.

Causes
Cylindromas can be sporadic or inherited.

Diagnosis
Computed tomography or magnetic resonance imaging provide the best representation of the tumour's extension.

Treatment
Surgical excision is used to treat cylindromas.
