RESUMO
Gluteal artery aneurysms are uncommon among all aneurysms and are usually a result of trauma. Streptococcus viridans bacteremia has been described in rare cases of extracranial mycotic aneurysms. Despite a variable clinical presentation, mycotic aneurysms of the superior gluteal artery could be the cause in patients with unexplained sciatica pain. Here we report a very rare case of spontaneous rupture of a superior gluteal artery mycotic aneurysm in a patient with underlying infective endocarditis (IE) secondary to Streptococcus viridans.

Primary subglottic malignant melanoma is a very rare and underdiagnosed neoplasm. We are reporting a case of primary malignant melanoma of subglottic mucosa in a 78-year-old woman who presented to our hospital with shortness of breath and hoarseness of voice. Laryngoscopy and excisional biopsy along with immunoreactivity to S-100 and human melanoma black-45 (HMB-45) confirmed the diagnosis. The patient was treated with laryngectomy followed by radiotherapy. Five years following surgical treatment, she continues to be asymptomatic. To our knowledge, there is only one reported case of primary malignant melanoma of subglottic mucosa in the medical literatures.
