Subcutaneous nodules in children: Don't forget deep granuloma annulare: A Case Report.

Deep granuloma annulare is an uncommon benign granulomatous skin disorder that presents almost exclusively in the paediatric population. It presents as an asymptomatic subcutaneous nodule with normal overlying skin on distal extremities, the scalp, or the forehead. It shows a deep palisading granuloma with areas of central necrobiosis on histologic examination. Due to its self-limited nature, clinical follow-up is recommended over surgical interventions. We present a case of cephalic deep granuloma annulare in a healthy 5-year-old girl who remains free of recurrence after surgical excision at the 6-month follow-up. Our case emphasizes the importance of differentiating the lesion from its clinical and histopathological mimickers, such as the rheumatoid nodule. The awareness of this entity is important to avoid the overinvestigation and overtreatment of a benign and self-limited disease.
