RESUMEN
Introduction: Balanitis is an inflammation of the glans penis. Balanoposthitis involves both the glans penis and prepuce and occurs only in uncircumcised males. Recurrent balanoposthitis represents a strong indication for circumcision. After Candida infections, aerobic bacteria are the second most common aetiological cause of acute infectious balanoposthitis, mainly streptococci groups B and D, and staphylococci, usually S. aureus . Their clinical manifestations are variable inflammatory changes, including diffuse erythema and oedema. Severe balanopreputial oedema with purulent exudate occurs in painful, erosive streptococcal balanoposthitis.Coagulase-negative staphylococci (CoNS) are commensal skin bacteria, but are also recognized pathogens of the genitourinary system, mainly related to urinary tract infections. Staphylococcus haemolyticus is one of the main species of CoNS that is part of the cutaneous microflora but is also associated with nosocomial infections. In addition, S. haemolyticus also causes other infections of the male urogenital tract, such as chronic prostatitis and epididymo-orchitis, but it has not been associated with balanitis. Case presentation: A 45-year-old man reports having suffered several episodes of balanoposthitis in the last 3 years, which were treated with topical antifungal treatments alone or associated with corticosteroids. For this reason, he underwent a postectomy by his urologist 8 months ago to avoid further recurrences.The patient consulted for an episode of painful, erosive and exudative lesions on the glans penis and over the post-operative scars lasting 5 days. He had no urinary discomfort or inguinal lymphadenopathy. A complete blood count, biochemical analysis, C-reactive protein (CRP), prostate-specific antigen (PSA) and urinalysis were normal. Abundant growth of S. haemolyticus was obtained in the culture on tryptone soya agar with sheep blood and chocolate agar with Vitox media. The MicroScan panel CIM 37 (PM37) was used to study the antimicrobial susceptibilities of the isolated bacteria. The fungal culture on Sabouraud dextrose agar was negative. Based on the antimicrobial susceptibility study, treatment with oral ciprofloxacin and topical mupirocin was started, and the genital infection was completely cured. Conclusion: We present a healthy, non-diabetic, circumcised male patient with severe, erosive and painful balanitis probably due to S. haemolyticus .
RESUMEN
Myxoinflammatory fibroblastic sarcoma of the soft tissues is a rare low-grade tumor of uncertain origin that most often occurs on the extremities of adults. The tumor predominantly involves the subcutaneous tissues of the hands and feet. Despite being a rare neoplasm, owing to its varied histologic appearance, myxoinflammatory fibroblastic sarcoma should be differentiated from various benign and malignant soft-tissue lesions. Myxoinflammatory fibroblastic sarcoma has been well described in pathology journals but not in the surgical literature. We report a case of myxoinflammatory fibroblastic sarcoma in a 19-year-old man with a plantar ulcer lesion in his left foot. To our knowledge, this is the first reported case in the literature involving the epidermis.
