Terry's nails are characterized by white opacification of the nails with effacement of the lunula and distal sparing. Described originally in 1954 by Dr. Richard Terry as a common fingernail abnormality in patients with hepatic cirrhosis, Terry's nails are now a known sequelae of other conditions such as congestive heart failure, chronic kidney disease, diabetes mellitus, and malnutrition. Often all nails of the hands are affected. Treatment of the underlying disease may result in resolution. We present a case of a 77-year-old man who developed Terry's nails following an acute gastrointestinal bleed and subsequent hemorrhagic shock. The development of Terry's nails after a gastrointestinal bleed has not been previously reported.In rare instances, calcific tendonitis may manifest in the pediatric population as inflammatory calcium hydroxyapatite deposition. To our knowledge, there have been no previous case reports involving the flexor pollicis longus tendon at the thumb interphalangeal joint. We present a 9-year-old boy with a painful mass at the right thumb interphalangeal joint. Initial radiographs revealed a 7-mm ovoid calcific mass along the volar soft tissues of the thumb interphalangeal joint. Subsequent ultrasound and magnetic resonance findings further confirmed calcification with surrounding edema. Because the pain was limiting the patient's school activities, his family elected for excisional biopsy of the calcific mass. Pathology ultimately revealed prominent dystrophic calcifications with surrounding granulomatous inflammation, consistent with calcific tendonitis.We describe a giant cell tumor in a 74-year-old man who presented with pain and swelling in the left thumb. Radiographs of the left hand showed some lytic changes at the tip of the thumb. Magnetic resonance imaging suggested the diagnosis of giant cell tumor, which was later confirmed by biopsy. A good treatment response was achieved with disarticulation of the interphalangeal joint and amputation of the distal phalanx of the left thumb.We present a case of Helicobacter pylori-negative rectal mucosa-associated lymphoid tissue (MALT) lymphoma found on colonoscopy done for colorectal cancer screening. The lesion was successfully removed with endoscopic mucosal resection alone, without concomitant antibacterial treatment. On surveillance exams, the patient has had a 5-year disease-free survival. While prior reports highlight use of multiple modalities, this is the only case we are aware of in which treatment with endoscopic mucosal resection alone without antimicrobial therapy led to disease-free survival at 5 years.Ring chromosomes are uncommon in hematological diseases. Here we present the case of a 13-year-old girl with leukocytosis, anemia, and lymphadenopathy. Flow cytometry analysis revealed a predominant precursor T lymphoid population expressing CD7, CD5, CD2, and cytoplasmic CD3 with partial expression of CD33, CD34, CD117, and CD11c; TdT was positive, and myeloperoxidase was negative. The bone marrow aspirate showed markedly increased blasts that were positive for CD3, CD7, CD34, TdT, and myeloperoxidase (rare positivity) by immunohistochemistry stain, consistent with T-cell acute lymphoblastic leukemia (T-ALL) extensively involving a hypercellular marrow for age. The karyotype showed a ring 7 in 12 of the 21 metaphase cells examined and deletions of the subtelomeric regions on chromosome 7. Deletions in the short arm of chromosome 7 and the long arm of chromosome 7 are present in 2% to 4% of pediatric T-ALL cases. Ring chromosome 7 is typically seen in myeloid malignancies, including acute myeloid leukemia.Xp11 translocation renal cell carcinoma (RCC) accounts for most pediatric cases of RCC but is uncommon in adults. It has an aggressive course in adults with poor response to chemoradiation. We describe a 64-year-old man with Xp11 translocation RCC who achieved complete remission following surgery and chemoimmunotherapy.Villous adenoma of the genitourinary system is rarely encountered by the general urologist. Although commonly seen in a colorectal practice, this tumor has been infrequently described in the urethra or bladder. In the genitourinary tract, this tumor appears to have excellent survival when isolated; however, it does have an association with adenocarcinoma of the genitourinary or gastrointestinal tract. Here we present a case of villous adenoma of the urethra managed with a multidisciplinary approach, which led to discovery of invasive adenocarcinoma of the rectum.Episodic (recurrent) macroscopic hematuria in patients with IgA nephropathy is usually associated with a benign prognosis, although some patients experience a transient fall in glomerular filtration rate during the episodes. We present a 15-year-old girl with mild IgA nephropathy who had multiple episodes of macroscopic hematuria associated with severe but transient decreases in estimated glomerular filtration rate, low levels of serum uric acid, and marked increases in fractional excretion of uric acid. Ultrasound studies showed marked inflammatory changes in the bladder, especially involving the trigone. Cystoscopic findings were consistent with these changes. PF-06650833 inhibitor We hypothesize that the macroscopic hematuria may have resulted, at least in part, from hyperuricosuria causing acute irritation of the bladder mucosa in the trigone area.Infective endocarditis is a significant cause of morbidity and mortality in hospitalized patients, especially with the increasing use of indwelling catheters in critically ill children. Surgical excision is sometimes essential to relieve valvar dysfunction and reduce burden of infection. Here we present a preterm infant who developed refractory infective endocarditis and right heart failure with tricuspid valve vegetation likely related to an indwelling umbilical venous catheter. Infective endocarditis resolved after resection of the vegetation and tricuspid valve repair, followed by a 6-week course of antibiotics.Cardiogenic pulmonary edema classically presents bilaterally and with a symmetric distribution. Occasionally, cardiogenic pulmonary edema can present unilaterally, which carries an independent risk for mortality, possibly due to the delayed diagnosis. The most common cardiogenic cause of unilateral pulmonary edema is acute mitral regurgitation, frequently described in the setting of acute coronary syndrome. Here we describe a case of unilateral pulmonary edema caused by acute mitral regurgitation outside the setting of acute coronary syndrome.
