Subcutaneous sarcoidosis: a case series from a single center

Abstract

Background: Sarcoidosis is a multisystemic granulomatous disease which not only affect the skin but can also involve the lymph nodes, eyes, and lungs. Subcutaneous sarcoidosis (SCS), is a rare form of sarcoidosis which is generally more prevalent in women in their 40s and 50s, characterized by subcutaneous, flesh-colored nodules, mostly localized on the limbs. A retrospective study to investigate clinical features and response to treatment in patients affected by SCS.

Methods: All patients with systemic and/or cutaneous sarcoidosis visited in our clinic hospital between 2012 and 2022. Out of this group, clinical features, and management of SCS patients were analyzed.

Results: Out of 102 patients with specific lesions of cutaneous sarcoidosis, with or without systemic involvement, 13 (13%) were diagnosed with SCS.

Conclusions: Our study confirms that systemic involvement in SCS is the prevalent finding as expected. Moreover, SCS patients have a relatively good prognosis, and systemic treatment does not differ from first-line therapies for cutaneous sarcoidosis.
