RESUMO
INTRODUCTION AND IMPORTANCE: Abdominal actinomycetoma is a rare and often a missed diagnosis by most of clinicians due to its rarity and different clinical presentations. It is caused by Actinomyces speces which are gram positive bacilli and normal commensal inhabitants of the human bronchial and gastrointestinal tracts. A.Israelli is responsible for disease in humans once the mucosal barrier is broken. CASE PRESENTATION: This case report presents an adult female patient who consulted for a localized abdominal wall mass of 3 weeks duration and the clinical exam was in favor of an abdominal wall abscess, but later found to be an actinomycotoma of the colon invading the abdominal wall and forming an abdominal wall abscess. Transverse colectomy and drainage of abscess was done and she improved well. CLINICAL DISCUSSION: Actinomycosis is common in the tropical and subtropical area. However, this is the first case reported in Rwanda and prompt surgical treatment and antibiotherapy have led to a good clinical outcome. CONCLUSION: Abdominal actinomycetoma should be considered as a differential diagnosis of any abdominal wall mass for patients with known risk factors and surgery and antibiotics are the only curative treatment.
RESUMO
Metaplastic breast carcinoma is a rare and aggressive condition, accounting less than 1% of breast malignancies. It presents with large mass and frequently with distant metastasis at time of diagnosis. Morphologically, it is characterized by the differentiation of neoplastic epithelium into epithelial or mesenchymal-looking elements like squamous cells, spindle cells, cartilage, or bone and has poor prognosis with its triple negative status.
