Summary
Scar sarcoidosis, a rare condition, can manifest as nodules on knee scars. Inflammatory changes in existing scars may signal the onset of this uncommon disease.
Area of Science:
- Dermatology
- Pulmonology
- Pathology
Background:
- Scar sarcoidosis is an uncommon manifestation of sarcoidosis.
- It presents with inflammatory changes localized to pre-existing scars.
- The pathogenesis and clinical presentation are not fully understood.
Purpose of the Study:
- To report a rare case of scar sarcoidosis.
- To highlight the clinical and diagnostic features of this condition.
- To discuss potential indicators for disease onset.
Main Methods:
- Clinical examination of skin lesions.
- Dermatological assessment including palpation and visual inspection.
- Imaging studies: Computed tomography (CT) of the chest.
- Histopathological examination of skin biopsy.
Main Results:
- A 70-year-old female presented with knee scar swelling and nodules.
- Dermatological exam revealed erythematous papules and subcutaneous nodules.
- Chest CT showed pulmonary tubercles and enlarged mediastinal lymph nodes.
- Skin biopsy confirmed non-caseating granulomas in the dermis.
Conclusions:
- The patient was diagnosed with scar sarcoidosis.
- This case underscores the importance of recognizing scar sarcoidosis.
- Inflammatory alterations in scars may serve as early indicators for sarcoidosis onset.
