Primary cutaneous angioplasmocellular hyperplasia.

Area of Science:

• Dermatology
• Pathology
• Oncology

Background:

• Primary cutaneous angioplasmocellular hyperplasia is an exceptionally rare plasma-cellular infiltrate.
• Previous reports are limited, with only one case documented in the literature involving two patients.

Observation:

• A 62-year-old Caucasian male presented with a solitary nodule on the posterior neck.
• The patient was systemically well at the time of presentation.
• Histopathological examination revealed a vascular proliferative process characterized by abundant plasma cells within the stroma.

Findings:

• The lesion demonstrated a unique combination of vascular proliferation and plasma cell infiltration.
• Histological findings were consistent with the diagnosis of primary cutaneous angioplasmocellular hyperplasia.
• Complete resolution was achieved following surgical excision (curettage and diathermy).

Implications:

• This case expands the understanding of primary cutaneous angioplasmocellular hyperplasia, a rare cutaneous neoplasm.
• It highlights the importance of accurate clinicopathological correlation for diagnosing rare dermatological conditions.
• The successful outcome suggests that surgical management can be effective for this condition.
