Solitary Violaceous Nodule on the Face.

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Dermal cylindroma, also known as turban tumor, is a rare, benign adnexal neoplasm.
• These tumors typically present as smooth, firm, pink-to-red dermal nodules.

Purpose of the Study:

• To present a case of dermal cylindroma.
• To highlight the clinical presentation and diagnostic considerations for this uncommon skin tumor.

Main Methods:

• A 77-year-old male presented with a several-year history of an asymptomatic preauricular papule.
• Physical examination revealed a solitary, plum-colored dermal nodule.
• A shave biopsy was performed for histopathological examination.

Main Results:

• The lesion was a 1.5 cm, well-circumscribed dermal nodule.
• Histopathological analysis confirmed the diagnosis of dermal cylindroma.
• No lymphadenopathy or other significant findings were noted.

Conclusions:

• Dermal cylindroma is a distinctive but uncommon skin tumor.
• Early and accurate diagnosis is crucial for appropriate management.
• This case underscores the importance of considering rare skin neoplasms in differential diagnoses.
