Buried bumper syndrome (BBS) is an uncommon complication of percutaneous endoscopic gastrostomy (PEG) tube placement. This unusual phenomenon occurs when the internal bumper of a PEG tube erodes and migrates through the gastric wall and becomes lodged anywhere between the gastric wall and the skin. If not removed and treated appropriately, it can lead to life-threatening complications. It is considered to be a late complication, with most cases occurring from months to years later. We present an unusual case of a very rapid development of BBS, along with a brief review of contributing factors and treatment recommendations.
Histoplasmosis is endemic to the midwestern and east central states in the United States near the Mississippi and the Ohio River valleys. Ninety-nine percent of patients exposed to histoplasmosis develop only subclinical infection. Liver involvement as a part of disseminated histoplasmosis is well known; however, isolated hepatic histoplasmosis without any other stigmata of dissemination is extremely rare and the literature is limited to only two case reports. We present a rare case of isolated granulomatous hepatitis due to histoplasmosis in a 35-year-old female with dermatomyositis receiving low-dose prednisone and methotrexate. There was no evidence of fungal dissemination elsewhere. High clinical suspicion is critical for early diagnosis and treatment.
Introduction Renal cell carcinoma (RCC) constitutes 3% of all adult malignancies and often presents insidiously. Consequently, 25-30% of patients have metastases at the time of diagnosis. Discussion Gastrointestinal (GI) bleeding from RCC metastases is an uncommon and underrecognized manifestation of this disease. We hereby report a rare case of RCC with stomach metastasis which heralded the primary manifestation of the disease. This case highlights the importance of maintaining vigilance for unusual causes during endoscopy in cases of upper GI hemorrhage.Keywords renal cell carcinoma . upper gastrointestinal bleeding . stomach metastasis . initial presentation Case ReportA 53-year-old male presented to the emergency room with 1 week history of melena, generalized fatigue, and dizziness. Other significant medical problems included coronary artery disease, type 2 diabetes, hypertension, dyslipidemia, and chronic obstructive pulmonary disease. He was an ex-smoker with a 40-pack yearcigarette smoking history. Medications included aspirin, metoprolol, simvastatin, and metformin. He denied recent use of over-the-counter or nonsteroidal antiinflammatory medications. Physical examination revealed a cachectic pale gentleman who was in moderate distress. Blood pressure was 70/50 mm Hg and heart rate was 130 beats/min. Heart and lungs were normal. Abdominal examination revealed mild epigastric tenderness to deep palpation. There was no rebound tenderness or guarding or palpable masses. Laboratory tests revealed hemoglobin of 6.3 g/dl (13.8-17.2 g/dl) with microcytic picture, hematocrit of 19.5% (41-50%), blood urea nitrogen of 74 mg/dl (3-29 mg/dl), creatinine of 3.0 mg/dl (0.5-1.4 mg/dl), and calcium of 14.6 mg/dl (8.5-10.4 mg/dl). Urinalysis did not reveal any red blood cells. White blood count, platelets, and coagulation studies were all normal. After initial resuscitation, an emergent esophagogastroduodenoscopy was performed. A 1.5-cm vascular polypoid mass was noted in the fundus of the stomach (Fig. 1a, b), which was biopsied. No other lesions were noted in the esophagus and the duodenum. Histology from the stomach mass revealed small, vacuolated, clear cells highlighted by immunostaining with AE 1/3, CA 9, and CD 10 and showed strong reactivity with Vimentin ( Fig. 2a-c). These findings confirmed the diagnosis of clear cell subtype metastatic renal cell carcinoma (RCC). Subsequent computed tomography (CT) of the abdomen revealed a 5×7.4-cm ill-defined mass in the inferior pole of the right kidney, multiple pulmonary nodules, and osteolytic lesions involving multiple vertebrae and sternum suggestive of primary renal cancer with metastatic disease (Fig. 3a, b). Because of the extensive metastatic disease, palliative therapy options were discussed with the patient but he declined any further interventions and opted for
Mild hypokalemia is common and encountered in a multitude of diseases, but severe hypokalemia leading to rhabdomyolysis is relatively rare. The watery diarrhea, hypokalemia, achlorhydria (WDHA) syndrome caused by vasoactive intestinal polypeptide (VIP)-producing tumors, is an extremely rare cause of hypokalemic rhabdomyolysis and the literature is limited to one case report. We report a second case of an adult who presented with rhabdomyolysis due to severe hypokalemia. Further evaluation revealed that he had a VIP-producing pancreatic neuroendocrine tumor (NET), which was the cause of his hypokalemic rhabdomyolysis. Although rare in occurrence, a high index of suspicion is of paramount importance for establishing the correct diagnosis and treatment.
