Hidradenitis supurativa prepuberal: presentación de 2 casos clínicos / Prepubertal Hidradenitis suppurativa: Report of 2 clinical cases

La hidradenitis supurativa (HS) es una enfermedad inflamatoria de la piel, caracterizada por la aparición de nódulos profundos en zonas que poseen glándulas apocrinas. Aparece más frecuentemente en mujeres entre la segunda y la tercera década de la vida. Objetivo Reportar 2 pacientes portadoras de HS a edad prepuberal. Caso 1 Paciente de sexo femenino, 10 años de edad, Tanner I-II, con antecedentes de obesidad. Consultó por un cuadro de 4 meses de evolución caracterizado por lesiones recurrentes en región inguinal bilateral que ocasionalmente drenan material purulento. Se diagnosticó HS Hurley I, se trató con antibióticos tópicos y manejo nutricional, con buena respuesta. Caso 2 Paciente de sexo femenino, 10 años de edad, Tanner I-II, con antecedentes de obesidad. Consultó desde los 6 años por cuadros recurrentes de lesiones en cara interna de muslo izquierdo. Fue tratada con múltiples cursos de antibióticos con escasa respuesta. Se diagnosticó HS Hurley I y se decidió manejo con terapia fotodinámica y apoyo nutricional, con buena respuesta. Conclusiones La etiología de la HS no es clara. La presentación a edades tempranas se asocia a antecedentes familiares y compromiso más extenso a futuro. El tratamiento de la enfermedad depende de cada caso, no existiendo un protocolo establecido.

Hidradenitis suppurativa (HS) is an inflammatory follicular skin disease. It usually presents as recurrent, deep nodules in flexural apocrine gland bearing areas. It appears mainly in women, in the second and third decade of life. Objective To present 2 cases of patients with prepuberal HS. Case 1 A 10-year old female, Tanner stage I-II and obesity. History of 4 months of evolution with bilateral recurrent groin lesions that occasionally drain pus; HS Hurley stage I was diagnosed, and topical antibiotics and nutritional management were prescribed, with a good response. Case 2 A 10 years old female, Tanner stage I-II and obesity. Since the age of 6 years, recurrent episodes of lesions in the inner side of the left thigh were observed, and multiple antibiotics with poor response were prescribed. HS Hurley stage I was diagnosed, and photodynamic therapy and nutritional management were used, with good response. Conclusions The etiology of HS is unclear. Usually the presentation at early age is associated with a family history and more extensive compromise in the future. Treatment is difficult and depends on each case and severity.

Síndrome de POEMS con lesión lítica aislada y hemangiomas glomeruloides: caso clínico / POEMS syndrome with an isolated lytic lesion and glomeruloid hemangiomas: report of one case

POEMS syndrome (polyneuropathy, organomegaly, endocrine abnormality, M-protein, plasma cell dyscrasia, and skin lesions) is a rare atypical plasma cell dyscrasia with characteristic para neoplastic manifestations. Glomeruloid hemangioma is a typical skin change pathogenetically related with elevated levels of Vascular Endothelial Growth Factor (VEGF). We report a 69 year-old woman that presented cachexia associated with diabetes, hypothyroidism and severe sensitive motor polyneuropathy. Her skin changes included hyper pigmentation, acrocyanosis and glomeruloid hemangioma. The subsequent study revealed a monoclonal gammopathy lambda type; a unique lytic vertebral lesion and a clonal plasma cell proliferation. Treatment with prednisone 0.5 mg/kg and melphalan 0,25 mg/kg in cycles of 4 days every 4 weeks was started, but the patient was lost from follow up.

Sarcoma histiocítico cutáneo: Reporte de un caso / Cutaneous histiocytic sarcoma: Report of one case

Histiocytic sarcoma (HS) is a rare hematologic malignancy with morphologic and immunophenotypic evidence of histiocytic differentiation. Previously known as "true histiocytic lymphoma", the tumor follows an aggressive clinical course. Involvement of lymph nodes, skin, and extranodal sites has been described. Among the latter, approximately 29 cases involving the skin have been reported. On pathology, the lesion shows a diffuse proliferation of large epitheloid histiocytes with marked pleomorphism. We report a 78 year-old male who presented with a nodular lesion in the forehead, involving the skin and son tissue. The pathological diagnosis was a HS. The patient waslost from follow up.
