Xantogranuloma necrobiótico. Diagnóstico diferencial, tratamiento e implicaciones sistémicas. A propósito de un caso / Necrobiotic xanthogranuloma. Differential diagnosis, treatment and systemic involvement. Case report

CASO CLÍNICO: Varón de 48 años remitido por edema palpebral con nódulos ulcerados amarillentos en ambos párpados superiores. Las técnicas de imagen demostraron infiltración en ambas órbitas anteriores que fueron biopsiadas con el resultado de xantogranuloma necrobiótico. En el estudio sistémico se halló una gammapatía monoclonal IgG no conocida. Se inició tratamiento con corticoides y ciclosporina orales sin éxito, por lo que se pautaron inyecciones intralesionales de triamcinolona que controlaron la enfermedad orbitaria. Discusión: El xantogranuloma necrobiótico es una rara entidad que suele afectar a párpados y órbita anterior. Su diagnóstico es importante porque se asocia a procesos linfoproliferativos malignos. Los corticoides intralesionales fueron efectivos en su manejo

CASE REPORT: A 48-year-old male was referred to our hospital for further evaluation of eyelid edema with bilateral yellowish ulcerated nodules. Suspecting a xanthogranulomatosis, imaging tests and biopsy were performed with diagnosis of necrobiotic xanthogranuloma. IgG monoclonal gammapathy was diagnosed in a systemic study. Systemic corticosteroids and cyclosporine were initiated unsuccessfully; therefore intra-lesional injections of triamcinolone were started, which controlled the orbital disease. Discussion: Necrobiotic xanthogranuloma is a rare condition that usually affects the eyelids and anterior orbit. Its diagnosis is important as it is associated with malignant lymphoproliferative processes. Intra-lesional corticosteroids were effective in our patient

Orbital and myocardial metastases of a primary pulmonary melanotic schwannoma

We present the case of a 60-year-old man with a primary pulmonary melanotic schwannoma treated with surgery and who developed an orbital and myocardial relapse 2 years after the initial diagnosis. Melanotic schwannomas are rare pigmented tumours that tend to arise from the peripheral nerves near the midline. A primary lung presentation, as in our case, is extremely rare. In more than half of cases, the Carney triad of myxomas of the heart, skin and breast, spotty pigmentation and endocrine hyperactivity is present. A thorough pathological study is pivotal for a correct diagnosis. The main differential diagnosis is with metastases of malignant melanoma. The biological behaviour is unpredictable. Treatment should include radical surgery if possible; the role of chemotherapy and radiotherapy is uncertain due to the rarity of the tumour (AU)
