Histopathological changes in epithelium of hair follicles and acrosyringium caused by measles in child

Abstract Some epidermal alterations in measles has been described, such as keratinocytes apoptotic, parakeratosis, giant-cell formation, intranuclear and cytoplasmic inclusions, dyskeratosis, spongiosis, and intracellular edema. The authors report for the first time in human a case of measles with the presence of multinucleated giant cells in the hair follicle and dyskeratosis in acrosyringium.

Syphilis associated with paretic neurosyphilis mimicking Reiter’s syndrome in HIV-infected patients

HIV/syphilis co-infection is common because both conditions affect similar risk groups. HIV interferes with the natural history of syphilis, which often has atypical clinical features and nervous system involvement in the early stage of disease. We report the case of an HIV-positive patient with secondary syphilis, scaling palmoplantar keratoderma, scrotal eczema, balanitis and urethritis mimicking Reiter’s syndrome. Immunohistochemistry using polyclonal antibodies against Treponema pallidum revealed the presence of spirochetes, associated with the paretic form of parenchymal neurosyphilis. The patient was given crystalline penicillin, with complete resolution of dermatological and neurological symptoms, and no sequelae.

Poorly differentiated synovial sarcoma in the wrist - Case report

Synovial sarcomas are rare malignant tumors affecting mainly young adults, presenting as a slow growth mass located in deep soft tissues of extremities, near the joints. In this report a 34-year-old male patient, presented an ulcerovegetative lesion on the right wrist which was completely excised. Histopathology and immunohistochemistry confirmed synovial sarcomas with poorly differentiated cells. This patient presented 11 months later with ipsilateral axillary lymph node metastasis, which emphasizes the unfavorable prognosis of this synovial sarcoma variant. The indolent growth pattern of this sarcoma justifies the well circumscribed initial stages, which progressively infiltrate adjacent structures with lung metastasis (80%) and lymph node involvement (20%) and thus corroborates the importance of early diagnosis and proper treatment.

Chromoblastomycosis: an exuberant case

Chromoblastomycosis is a chronic subcutaneous mycotic infection caused by dematiaceous saprophytic moulds. The most frequently isolated agent is Fonsecae pedrosoi. This article reports a case of a man from the Amazon region in Northern Brazil who presented with a lesion of 12 months' duration, which gradually increased in size until covering the majority of his right leg. A successful treatment with itraconazole was performed.

Tumor triquilemal proliferante gigante com fechamento por retalho miocutâneo bilateral de grande dorsal / Giant prolliferating trichilemmal tumor with latissimus dorsi bilateral myocutaneous flap closure

Paciente do sexo masculino, 54 anos de idade com diagnóstico de tumor triquilemal gigante recidivante localizado no dorso, com cirurgia prévia realizada há seis anos. Após exérese da lesão com margem de 1cm, foi realizada reconstrução com retalho miocutâneo bilateral do músculo grande dorsal, com fechamento da ferida operatória. Descrevemos neste relato características clinicoepidemiológicas do tumor triquilemal, assim como as opções terapêuticas.

This article reports the case of a 54-year-old male patient diagnosed with a recurrent gigantic trichilemmal tumor on the back, having undergone surgery six years earlier. After the exeresis of the lesion (with 1 cm margins), econstruction was carried out using a bilateral myocutaneous flap from the latissimus dorsi muscle to close the surgical wound. This report describes the clinical-epidemic characteristics of trichilemmal tumors, as well as treatment options.

Aplicação da dermatoscopia no auxílio diagnóstico da ocronose exógena / Use of dermoscopy for diagnosis of exogenous ochronosis

A ocronose exógena consiste em hiperpigmentação crônica de áreas previamente tratadas com agentes tópicos como: a hidroquinona, a resorcina, os antimaláricos e o fenol. O diagnóstico precoce permite suspender prontamente o agente causador, uma vez que as opções terapêuticas disponíveis são escassas e com resultados insatisfatórios. Reportam-se três casos de ocronose exógena na face, diagnosticados pela dermatoscopia. O estudo dermatoscópico evidenciou estruturas amorfas de coloração cinza-enegrecido, algumas obliterando as aberturas foliculares. O exame histopatológico corroborou o diagnóstico.

Exogenous ochronosis consists of chronic hyperpigmentation of areas previously treated with topical agents such as hydroquinone, resorcinol, antimalarials and phenol. Early diagnosis allows to promptly suspend the causative agent and it is imperative since the available therapeutic options are scarce and have presented so far unsatisfactory results. Three cases of exogenous ochronosis on the face which were diagnosed with the use of dermoscopy are presented. Dermatoscopy showed blackish-gray amorphous structures, some obliterating the follicular openings. Histopathological examination confirmed the diagnosis.

Long-term outcome of neuroparacoccidioidomycosis treatment / Resultado de longo prazo no tratamento da neuroparacoccidioidomicose

INTRODUCTION: Neuroparacoccidioidomycosis (NPCM) is a term used to describe the invasion of the central nervous system by the pathogenic fungus Paracoccidioides brasiliensis. NPCM has been described sporadically in some case reports and small case series, with little or no focus on treatment outcome and long-term follow-up. METHODS: All patients with NPCM from January 1991 to December 2006 were analyzed and were followed until December 2009. RESULTS: Fourteen (3.8 percent) cases of NPCM were identified out of 367 patients with paracoccidioidomycosis (PCM). A combination of oral fluconazole and sulfamethoxazole/trimethoprim (SMZ/TMP) was the regimen of choice, with no documented death due to Paracoccidioides brasiliensis infection. Residual neurological deficits were observed in 8 patients. Residual calcification was a common finding in neuroimaging follow-up. CONCLUSIONS: All the patients in this study responded positively to the association of oral fluconazole and sulfamethoxazole/trimethoprim, a regimen that should be considered a treatment option in cases of NPCM. Neurological sequela was a relatively common finding. For proper management of these patients, anticonvulsant treatment and physical therapy support were also needed.

INTRODUÇÃO: Neuroparacoccidioidomicose (NPCM) é um termo utilizado para descrever a invasão do sistema nervoso central pelo fungo patogênico Paracoccidioides brasiliensis. NPCM é descrita, esporadicamente, em relatos de casos ou pequenas séries de casos com pouco ou nenhum enfoque no tratamento ou acompanhamento de longo prazo. MÉTODOS: Todos os pacientes com diagnóstico de NPCM entre janeiro de 1991 a dezembro de 2006 foram acompanhados até dezembro de 2009. RESULTADOS: Foram identificados 14 (3,8 por cento) casos de NPCM de 367 pacientes com paracoccidioidomicose (PCM). Regime combinando fluconazol oral e sulfamethoxazol/trimetoprim (SMZ/TMP) foi o tratamento de escolha. Não houve nenhum caso de óbito causado pelo fungo Paracoccidioides brasiliensis.Sequela neurológica foi identificada em 8 pacientes. Durante o seguimento, calcificação residual foi um achado comum de neuroimagem. CONCLUSÕES: Todos os pacientes deste estudo responderam de forma favorável a associação do fluconazol com o sulfamethoxazol/trimetoprim, um esquema terapêutico que deve ser considerado nos casos de NPCM. Sequela neurológica foi um achado relativamente comum, desta forma, a utilização de anticonvulsivantes, assim como foi necessário suporte fisioterápico para um manejo adequado destes pacientes.

Dermatofitose por Tricophyton rubrum como infecção oportunista em pacientes com doença de Cushing / Dermatophytosis caused by Tricophyton rubrum as an opportunistic infection in patients with Cushing disease

O dermatófito Trichophyton rubrum é um agente comum nas micoses superficiais, podendo apresentar lesões extensas pauci-inflamatórias de evolução crônica, especialmente em imunocomprometidos. O hipercortisolismo, na síndrome de Cushing, aumenta o risco de infecções, resultado do efeito imunossupressor dos glicocorticóides. Os casos relatados apresentam duas formas distintas de dermatofitose, em pacientes com doença de Cushing, causadas por Tricophyton rubrum e posterior remissão após normalização da cortisolemia.

Trichophyton rubrum is a common agent found in superficial mycoses, which present ample nonin?ammatory lesions, with chronic evolution, especially in immunocompromised patients. The hypercortisolism in Cushing's syndrome increases the risk of infections as a result of the immunosuppressive effect of glucocorticoids. The reported cases here refer to two different types of dermatophytosis caused by Trichophyton rubrum in patients with Cushing's disease, resistant to antifungal treatment. The disease remitted after the levels of cortisol went back to normal.
