Background:

Cutaneous sarcoidosis presents with diverse clinical morphologies.
It often mimics other common dermatologic conditions, posing diagnostic challenges.
Early and accurate diagnosis is crucial for effective management.

Observation:

A 48-year-old woman presented with a 1-month history of sudden, generalized pruritic, violaceous papules.
The lesions were distributed across all extremities, trunk, and back.
The patient had an 8-year history of intermittent pruritic papules on her lower extremities.

Findings:

Histopathological examination of a biopsy specimen confirmed sarcoidosis.
Despite extensive skin lesions, the patient showed no evidence of systemic involvement.

The case highlights a rare presentation of sarcoidosis with widespread cutaneous manifestation.

Implications:

This case underscores the varied presentations of cutaneous sarcoidosis.
Recognizing sarcoidosis's mimicry of other dermatoses is vital for clinicians.
Further research into the pathogenesis and treatment of diverse sarcoidosis forms is warranted.
