Carcinosarcoma of the gallbladder-an exceedingly rare tumour.

Carcinosarcoma of the gallbladder (CSGB) is an extremely rare tumour that presents variable proportions of malignant epithelial and mesenchymal elements. Preoperative diagnosis of CSGB is challenging owing to its non-specific clinical presentation and imaging findings. The final diagnosis requires histopathological confirmation of both the epithelial and mesenchymal components. Owing to the low incidence and poor prognosis of this tumour, it is essential to gather all the individual experience-based information. We report a case of a 52-year-old female who presented with right upper abdominal pain and vomiting for 2 weeks and a painless palpable mass on the right upper quadrant of the abdomen. Imaging studies showed a complex gallbladder mass, which was pathologically confirmed to be CSGB. To our knowledge, this is the first CSGB presented from a radiological perspective. A short literature revision of CSGB is provided.

Diffuse Hepatic Hemangiomatosis in the Adult without Extra-hepatic Involvement: An Extremely Rare Occurrence.

We present a case of a pathologically proven multinodular diffuse hepatic hemangiomatosis (DHH) with no extra-hepatic involvement in a 68-year-old male. Cavernous hemangioma is the most common hepatic tumor. However, DHH, which is characterized by extensive replacement of liver parenchyma with hemangiomatous lesions, has been rarely reported in adults. The etiology and clinical course are not completely understood because of its rareness, although the diagnosis might be suggested by the magnetic resonance imaging findings.

[Painful scalp ulcers]. / Ulcerações dolorosas do couro cabeludo.

Temporal arteritis is a systemic vasculitis mainly affecting large and medium sized vessels, temporal artery in particular. The authors report the case of a male who presented with large painful scalp ulcers over the temporo-parietal area, ipsilateral headache, amaurosis fugax and jaw claudication. Temporal arteries were thickened, painful and pulseless. Laboratory work revealed erythrocyte sedimentation rate of 63 mm and normochromic and normocytic anaemia. On histopathology transmural acute and chronic inflammation and multiple giant cells were patent in temporal artery wall. Ophthalmologic observation revealed significant visual impairment, mainly on the right eye. Regarding temporal arthritis diagnosis, prednisolone 1 mg/Kg/day was introduced. Clinical improvement was outstanding, although visual impairment remained. This case emphasizes early diagnosis and treatment importance in the avoidance of definitive sequela.

Acute hepatitis associated with the use of levofloxacin.

BACKGROUND: Levofloxacin is a fluoroquinolone used globally to treat respiratory, skin, and genitourinary tract infections. It is generally well tolerated and there is a very low risk for liver injury in patients taking this antibiotic. OBJECTIVE: We report an acute case of hepatitis following treatment with levofloxacin for pneumonia. CASE SUMMARY: A 77-year-old white male (height, 162 cm; weight, 58 kg) with chronic bronchitis presented to the emergency department of the Hospital Curry Cabral, Lisbon, Portugal, with respiratory difficulty and productive cough. The patient had a history of chronic bronchitis, arterial hypertension, hypercholesterolemia, and benign prostatic hyperplasia, and was being treated with salmeterol 50 µg plus fluticasone 250 µg BID, and amlodipine 5 mg, simvastatin 20 mg, alfuzosin 10 mg, and finasteride 5 mg once daily. Initially, the patient refused admission and was sent home, medicated with levofloxacin 500 mg once daily (single dose) for pneumonia and acetaminophen 1 g (as needed, maximum TID) if axillary temperature exceeded 38.0°C (100.4°F). Three days later, the patient returned for a follow-up visit, and despite clinical and radiologic improvement, blood tests revealed a slight aggravation of anemia. On the seventh day of treatment with levofloxacin, the patient showed an elevation of transaminases. The temporal relation between the use of levofloxacin and the liver injury, the exclusion of other causes of hepatitis, and a compatible liver biopsy (conducted 14 days after identification of hepatitis) was consistent with the diagnosis of levofloxacin-associated hepatotoxicity. Levofloxacin treatment was stopped and the patient made a full recovery. The Naranjo Adverse Drug Reaction Probability Scale score for this association was "probable" (score 7) and the Roussel Uclaf Causality Assessment Method Scale score was "highly probable" (score 9). Unlike the 5 reported cases in the literature, this is the only case in which both a liver biopsy was performed in the course of the disease and the patient survived. CONCLUSION: The acute hepatitis observed in this elderly patient was probably associated with the administration of levofloxacin.

Blood loss anemia due to adenocarcinoma of the jejunum: case report and review of the literature.

BACKGROUND: Small bowel tumors are rare, accounting for only 3-6% of gastrointestinal neoplasms, 1-2% of these being malignant. They must be considered whenever a patient presents with gastrointestinal bleeding, with normal upper gastrointestinal endoscopy and colonoscopy. CASE PRESENTATION: We report a case of jejunal adenocarcinoma presenting as a blood loss anemia in a 65 year-old male, doing a brief review on the subject. CONCLUSION: Our case intends to highlight the fact that small bowel tumours are rare and frequently present to the Internist as non-specific clinical symptoms.
