A type of skin tumor originating from sweat glands

Classification
External resources

Acrospiroma is a type of skin tumor that originates from the sweat glands. These tumors are generally benign but can occasionally become malignant. Acrospiromas are part of a group of tumors known as sweat gland tumors, which also includes hidradenomas and poromas.

Classification

Acrospiromas are classified based on their histological characteristics and their origin from the eccrine sweat glands or apocrine sweat glands. They are often divided into two main types:

• Eccrine acrospiroma: Also known as hidradenoma, these tumors arise from the eccrine sweat glands, which are responsible for thermoregulation.
• Apocrine acrospiroma: These tumors originate from the apocrine sweat glands, which are associated with hair follicles and are found in areas such as the axillae and groin.

Clinical Presentation

Acrospiromas typically present as solitary, slow-growing nodules on the skin. They are most commonly found on the head, neck, and upper extremities. The nodules are usually firm and may be skin-colored, pink, or red. In some cases, they can become ulcerated or bleed.

Diagnosis

The diagnosis of acrospiroma is primarily based on histopathological examination. A biopsy of the lesion is performed, and the tissue is examined under a microscope. The histological features of acrospiroma include a well-circumscribed nodule with a mixture of solid and cystic areas. The tumor cells are typically small and uniform, with ductal differentiation.

Treatment

The primary treatment for acrospiroma is surgical excision. Complete removal of the tumor is usually curative, and recurrence is rare if the tumor is fully excised. In cases where the tumor is malignant, additional treatments such as radiation therapy or chemotherapy may be considered.

Prognosis

The prognosis for patients with acrospiroma is generally excellent, especially for benign tumors. Malignant acrospiromas, although rare, may have a more guarded prognosis and require more aggressive treatment.
