Tubular apocrine adenoma

Area of Science:

• Dermatopathology
• Oncology
• Surgical Pathology

Background:

• Tubular apocrine adenoma is a rare benign adnexal neoplasm.
• Syringocystadenoma papilliferum is another adnexal tumor with distinct histopathological features.
• Understanding the spectrum of adnexal tumors is crucial for accurate diagnosis and management.

Observation:

• A case of tubular apocrine adenoma of the scalp is presented.
• The superior portion of the lesion displayed characteristics consistent with syringocystadenoma papilliferum.
• Significant connective tissue involvement was noted within the tumor.

Findings:

• The presented case highlights a hybrid or morphologically overlapping adnexal neoplasm.
• The coexistence of tubular apocrine adenoma and syringocystadenoma papilliferum features is unusual.
• Connective tissue changes represent a notable feature of this specific tumor presentation.

Implications:

• This case expands the histopathological spectrum of scalp adnexal tumors.
• Recognizing such variations is important for differential diagnosis and treatment planning.
• Further research may elucidate the biological behavior and potential origins of these combined adnexal neoplasms.
