Tumor necrosis factor inhibitors for pediatric patients with SAPHO syndrome associated with acne conglobata.

Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is a rare chronic inflammatory disease with osteoarticular and cutaneous involvements as its main manifestations. Acne conglobata as a severe acne form may affect adolescent patients. Tumor necrosis factor inhibitors are usually used as a second-line therapy for refractory SAPHO syndrome and has been reported to treat acne conglobata successfully. We herein report three cases of adolescent patients with SAPHO syndrome associated with acne conglobata who were successfully treated with TNFi therapy.

Scrotal elephantiasis associated with follicular occlusion triad: A case report and literature review.

RATIONALE: Follicular occlusion triad (FOT) is an autosomal recessive inherited disease and no more than 3 variants of the triad have been reported. We give a report in which scrotal elephantiasis is a variant of FOT and further perform a literature review. PATIENT CONCERNS: A 41-year-old man came to us because of a large scrotal cyst and generalized skin lesions that had occurred over the past 10 years. The generalized skin lesions consisted of hidradenitis suppurativa on the perineum and back, acne conglobata in the armpit, and dissecting cellulitis of the scalp. He took antibiotics for a long time but achieved poor effect. Furthermore, he told his father and elder brother also manifested such skin lesions. DIAGNOSES: Magnetic resonance showed a mass in the left scrotum with clear boundaries. A routine blood test showed a high leukocyte level of 12 × 10/L and a hemoglobin content of 78 g/L. C-reactive-protein increased. Series of autoimmune antibody tests were negative. The postoperative pathologic findings showed that the mass was an epidermoid cyst, and hematoxylin and eosin staining showed hyperkeratosis of the skin as well as inflammatory and edematous changes. A diagnosis of a variant of FOT was made. INTERVENTIONS: We removed skin abscesses and lesioned the inner part with hydrogen peroxide. Then we performed an excision of the scrotal lesion. OUTCOME: The patient recovered well and had no evidence of recurrence at a 16-month follow-up. LESSONS: We reported a case in which scrotal elephantiasis was a variant of FOT and surgical intervention played an important role in secondary urologic diseases.

Síndrome SAPHO en la infancia. Presentación de un caso clínico / SAPHO syndrome in childhood. A case report

El acrónimo síndrome SAPHO (sinovitis, acné, pustulosis, hiperostosis y osteítis) engloba tanto manifestaciones cutáneas como muculoesqueléticas, entre ellas hiperostosis de los huesos y de las articulaciones de la pared torácica anterior, asociado a manifestaciones cutáneas; acné fulminans e hidradenitis supurativa. Los criterios diagnósticos no han sido validados en niños. El tratamiento inicial con antiinflamatorios no esteroideos en ocasiones es insuficiente y puede ser preciso asociar corticoides, fármacos modificadores de la enfermedad, antagonistas del factor de necrosis tumoral o bifosfonatos. Presentamos el caso clínico de un escolar con afectación poliarticular, osteoartritis de articulación esternoclavicular con importante componente inflamatorio y acné conglobata, con buena respuesta al tratamiento con pamidronato por vía intravenosa (AU)

The acronym of SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis and osteitis) combines a cluster of cutaneous and musculoskeletal manifestations, such as hyperostosis of bones of the anterior chest wall associated with acne fulminans and hidradenitis suppurativa. There are no validated diagnostic criteria in children. Nonsteroidal anti-inflammatory drugs are not always sufficient, and the use of corticosteroids, disease-modifying agents, tumor necrosis factor-α inhibitors or bisphosphonates may be necessary. We present the case of a child with polyarticular involvement, osteoarthritis of the sternoclavicular joint with severe inflammatory disorders and acne conglobata, with an excellent response to intravenous pamidronate (AU)

Familial Mediterranean fever patients with hidradenitis suppurativa.

BACKGROUND: Hidradenitis suppurativa (HS) has recently been described as a component of two autoinflammatory syndromes: PASH (pyoderma gangrenosum, acne, and HS) and PAPASH (pyoderma gangrenosum, acne, pyogenic arthritis, and HS). These associations together with others such as inflammatory bowel diseases suggest that defects in autoinflammatory pathways may play a role in the pathogenesis of HS. OBJECTIVES: To describe clinical and genetic characteristics of two unrelated patients with HS and familial Mediterranean fever (FMF). METHODS: Case study. RESULTS: Besides FMF and HS, the first patient had acne conglobata, and the second patient had pyoderma gangrenosum and ankylosing spondyloarthropathy. Both patients had M694V/V726A MEFV gene mutations. CONCLUSION: PASH and PAPASH have recently been associated with genetic alterations of gene encoding proline-serine-threonine phosphatase-interacting protein 1 (PSTPIP1), which interacts with the product of MEFV gene in the autoinflammatory pathway. This intriguing molecular interaction may explain shared phenotypic characteristics seen in genetic defects. Association of one more autoinflammatory disorders with HS adds another brick to the wall.

Síndrome de Sapho: relato de caso clínico / SAPHO syndrome: clinical case report

El síndrome de SAPHO es una condición relativamente rara, la cual designa varios desordenes que gana su nombre del epónimo por la sinovitis, acné, pustulosis, hiperostosis, osteítis. Relato de caso. Masculino, 15 años de edad, blanco, estudiante que hace dos años se encuentra en tratamiento por acné conglobata, que hace dos meses evoluciona con artralgia en pierna izquierda, tarsitis derecha y lumbalgia inflamatoria. Al examen físico se encuentra, palidez cutánea, pies invertidos y planos, rodillas en valgo, sacroileítis acentuada a la izquierda, tarsitis derecha, dolor en entesis (calcáneos) piel con lesiones cutáneas acneiformes extensas en rostro, dorso y tórax anterior. Exámenes complementarios: anemia normocitica y normo crómica, RX: sacro iliacas con señales de sacroileítis bilateral con psuedo alargamiento en la parte izquierda. USG de los pies normales, fondo de ojo: normal, HLAB27: negativa. Se inició indometacina y fisioterapia. Discusión: cuadro clínico de acné, artropatía inflamatoria característica del síndrome SAPHO, tratamiento conservador.

SAPHO syndrome is a relatively rare condition which designates several disorders that gain its name from the eponymous by synovitis, acne, pustular, hyperostosis, osteitis. Case report. Male, 15 years old, white, student who two years ago is in treatment for acne conglobata, who two months ago evolves with left leg arthralgia, right tarsitis and inflammatory low back pain. Physical examination includes skin paleness, inverted and flat feet, valgus knees, left sore sacroiliitis, right tarsitis, pain in entesis (calcaneus) skin with extensive acneiform skin lesions on face, dorsum and anterior thorax.
