PARACOCCIDIOIDOMYCOSIS IN A RENAL TRANSPLANT RECIPIENT

Paracoccidioidomycosis (PCM) is the most common endemic mycosis in Latin America. The etiological agents, which comprise two species, Paracoccidioides brasiliensis and P. lutzii, are thermodimorphic fungi that usually affect previously healthy adults. They primarily involve the lungs and then disseminate to other organs. Such mycosis is rare in organ transplant recipients; there have been only three cases reported in literature, until now. We report a case of PCM in a renal transplant recipient with an unusual dermatological presentation.

Nevus lipomatosus cutaneous superficialis

Nevus lipomatosus cutaneous superficialis is a rare benign hamartomatous skin tumor characterized by dermal deposition of mature adipose tissue. Two clinical forms have been described (classical and solitary types). We describe a case of nevus lipomatosus cutaneous superficialis with a 13-year history of growth in a young woman who had a solitary skin-colored tumoral mass on the right buttock. Histopathological findings were typical and confirmed the diagnosis. In this case, the lesion was a skin-colored isolated mass, as described in the solitary type, but its localization and age of appearance were compatible with the classical type. The combination of simultaneous clinical findings of both types had not been published before.

Merkel cell carcinoma in an immunosuppressed patient

Merkel cell carcinoma is an uncommon neuroendocrine carcinoma with a rising incidence and an aggressive behavior. It predominantly occurs in older patients, with onset occurring at a mean age of 75-80 years. Recognized risk factors are ultraviolet sunlight exposure, immunosuppression, and, more recently, Merkel cell polyomavirus. We report a case of Merkel cell carcinoma in a young HIV positive patient with Merkel Cell polyomavirus detected in the tumor.

Herpes zoster ophthalmicus after onabotulinumtoxin for cosmetic treatment: a case report

Herpes zoster outbreaks following minor procedures have been documented recently in literature. Since the use of botulinum toxin is nowadays spread in several medical areas for different purposes, it is crucial to study its side effects and complications. Literature review revealed 65 cases of zoster reactivation following minor procedures, and three cases related to BTA injections (two for facial lines treatment and one for chronic migraine). In our case, a 43 year old healthy woman had herpes zoster on the face and scalp after receiving BTA injections for cosmetic purpose, with complete recovery after anti-viral treatment.

Sweet's syndrome associated with Crohn's disease

Sweets syndrome is an uncommon benign skin disorder, whose pathogenesis remains unknown. Its classic form is more common in women and presents itself as papular-nodular, painful and erythematous or violaceous lesions. It mainly affects the face, neck, and upper limbs. Fever and neutrophilic leukocytosis are also common features. Although it is considered a systemic disease marker in more than half of patients, the association of this condition with Crohns disease is rare, with few cases reported in the literature, of which, none in Brazil. We report the case of a patient with Crohns disease who developed the classical features of Sweets syndrome.

Lichen planopilaris developed during childhood

Lichen planopilaris is a disease that appears with lymphocytic cicatricial alopecia. It is considered a follicular variant of lichen planus. The examination of affected areas shows alopecia with perifollicular erythema and scaling, revealing a predilection for hair follicles. The involvement of children is uncommon, with few reports in this population in the literature. This study presents a clinical case of a male patient of 15 years of age with characteristic lesions of lichen planopilaris.

Single cutaneous metastasis of colon adenocarcinoma - Case report

Skin metastases are relatively rare and occur most often when the cancer is already advanced, invading other organs. As to location, they often seem to elect areas located close to the primary tumor, although distant sites, such as the scalp, may be affected with some frequency. We present a case of a 76-year-old woman with colon adenocarcinoma that had a single metastatic lesion on the scalp.
