RESUMEN

Garcinia cambogia, a weight control herbal, can cause mild liver toxicity with nonspecific histologic changes. Herein, we reported a case of herbal-induced fulminant cholestatic giant cell hepatitis due to garcinia cambogia use. A 65-year-old woman with breast cancer treated 18 years earlier was admitted for obstructive jaundice for 2 weeks. She started using garcinia cambogia 3 months ago for weight loss. Physical exam showed scleral icterus. Serum studies excluded Wilson's disease, systemic infection including COVID-19 (coronavirus disease 2019), autoimmune hepatitis, and metabolic or toxicologic causes. An urgent liver biopsy showed severe giant cell hepatitis in absence of HSV-1/2, cytomegalovirus, HBsAg and HBcAg (immunostain), and EBV (in situ hybridization). Despite supportive therapy, the patient developed grade 2-3 hepatic encephalopathy and necessitated liver transplant. The explanted liver was markedly atrophy, in which the most striking histologic finding was diffuse distribution of multinucleated giant hepatocytes with syncytial pattern in a background of extensive zone-1 accentuated, geographic, hemorrhagic, confluent hepatocytic necrosis, along with remarkable hepatocytic and canalicular cholestasis. Marked hepatocellular and sinusoidal iron orverload present. The patient recovered uneventfully.

RESUMEN

The hepatic inflammatory myofibroblastic tumor is a spindle cell tumor of the liver that originates from the mesenchymal tissues. It is a rare benign tumor with the potential to degenerate into a malignant and invasive tumor. It can occur anywhere in the body with the most common sites being the lung, mesentery, and omentum. The most common types are myxoid, vascular pattern, fibrous, or hypocellular fibroid type. Immunohistochemistry staining often indicates vimentin, muscle-specific actin, smooth muscle actin, and cytokeratin. These tumors are positive for CD 68 abundant histiocytes but negative for S100. Half of the inflammatory myofibroblastic tumors contain a clonal cytogenetic aberration that activates the ALK gene expression. We present a rare case of HIMT in an elderly female with active primary squamous lung cancer.

RESUMEN

A 56-year-old female presented with abdominal pain, weight loss and fatigue. Computed tomography revealed an abdominopelvic mass and ascites. At surgery she had carcinomatosis and bilateral ovarian metastases arising from a cancer in a Meckel's diverticulum. Histology identified the primary to be a signet-ring cell adenocarcinoma within the Meckel's with ovarian metastases. This is the first report of a Krukenberg tumor from a Meckel's diverticulum. A discussion of malignancies within a Meckel's diverticulum is provided.

RESUMEN

Inflammatory myofibroblastic tumor (IMT) previously known as inflammatory pseudotumor, plasma cell granuloma, pseudosarcoma, myxoid hamartoma or inflammatory myofibrohistiocytic proliferation is recently recognized by World Health Organization (WHO) as "IMT" and is considered as a rare benign tumor of soft tissues occurring commonly in lung, liver and mesentry and omentum. IMT is mainly identified as a lesion of children and young population. In this report, we describe a rare case of IMT occurring in a 93-year-old female in urinary bladder with initial benign presentation but demonstrating rapid malignant transformation as confirmed with morphology and immunohistochemical (IHC) stains. Our report highlights the importance of close follow for IMT showing malignant transformation along with utility of IHC stains to evaluate the degree of malignant transformation in such cases.

RESUMEN

Patients with underlying chronic kidney disease (CKD) often have elevated serum calcium and parathyroid hormones due to compromised kidney function. We present a case of a 63-year-old female non-smoker with a surgical history of three renal transplants (at age 47, 51, and 58) along with thyroidectomy and parathyroidectomy, who came to the emergency department with complaints of a persistent dry cough and shortness of breath for the last two months. The patient had been on immunosuppressive drugs-tacrolimus, prednisolone, and mycophenolic acid-since her first renal transplant as well as on cinacalcet after parathyroidectomy (at age 54). An initial computed tomography (CT) scan demonstrated ground glass opacities in the bilateral upper lobes while bronchoscopy revealed few inflammatory cells without any fungi or bacteria. A repeat CT scan performed five days later due to rapid progression of her clinical symptoms showed worsening of ground glass opacities in the bilateral upper lobes and new nodules in the right middle and lower lung lobes. A wedge lung biopsy revealed metastatic pulmonary calcification (MPC) in the right upper lobe and non-specific interstitial pneumonia (NSIP) in the right lower lobe, confirming the co-existence of two different pathological processes most likely complicating the patient's clinical symptoms. Despite comprehensive medical therapy, the patient's symptoms progressively worsened and she is currently undergoing evaluation for both renal and lung transplants. Our case report not only presents a rare case of MPC coexisting with NSIP but also sheds light on the associated morbidity due to pulmonary symptoms in CKD patients.

RESUMEN

Adipose tissue is a normal anatomical finding in the heart but fat infiltration in cardiac valves is extremely rare with very few cases reported in the literature. We report a case of fatty infiltration in a mitral valve replaced for mitral valve prolapse causing severe mitral regurgitation in a 65-year-old male who presented with shortness of breath and upper respiratory tract infection. The histopathological examination of the mitral valve revealed sheets of mature adipocytes in the spongiosa layer leading to replacement of collagen and elastic fibers. The presence of adipocytes in the prolapsed valve could be considered to arise from the proliferation of pluripotent valvular interstitial cells. Herein, we have reviewed the previously reported cases of fatty infiltration in the mitral valve and discussed the pathogenesis and effect on valvular function.

RESUMEN

INTRODUCTION: High-risk HPV (hrHPV) testing is now considered standard of care in the detection and management of cervical high-grade squamous intraepithelial lesions (HSIL/CIN 2-3) and their precursors. Recently, there has been concern in the scientific literature and lay media about the lack of data regarding the false-negative rate (FNR) of HPV testing on SurePath(TM) cytology specimens. This is a critical issue, since guidelines on the management of Pap test abnormalities rely heavily on HPV status. We undertook this study to determine whether HPV testing on SurePath(TM) specimens is less sensitive compared to reports in the literature for ThinPrep®. METHODS: We identified women with new diagnoses of CIN 2, CIN 3, and squamous cell carcinoma (SCC) on biopsy or excision in 2009-2013. For each patient, we recorded all SurePath(TM) cytology and hrHPV HC2 (high-risk HPV Hybrid Capture 2) test results from within 5 years prior to histologic diagnosis. Using the histologic diagnosis as the gold standard, we calculated the sensitivities of cytology and hrHPV HC2 tests for the detection of CIN 2, 3, and SCC. Our findings are based only on women who underwent biopsy or excision after having an abnormal cytology and/or positive HPV result. RESULTS: In our cohort, the sensitivity of testing in the 5 years prior to histologic diagnosis of CIN 2, 3, and SCC (combined as a single group) is 98.4% for SurePath(TM) cytology, 95.3% for hrHPV HC2, and 100% if both tests are used together. No conclusion can be drawn regarding testing for SCC alone, because there was only one case of SCC. CONCLUSION: Our results show that the false-negative rate of hrHPV HC2 testing on SurePath(TM) specimens for the detection of CIN 2 and CIN 3 is low and comparable to that of ThinPrep® specimens.

RESUMEN

PATIENT: Female, 20 FINAL DIAGNOSIS: Papillary renal cell carcinoma Symptoms: Hemopthysis Medication: Sutent Clinical Procedure: CT guided biopsy Specialty: Oncology. OBJECTIVE: Rare disease. BACKGROUND: Papillary renal cell carcinoma (PRCC) is a rare disease and is a carcinoma of the renal tubular epithelium, comprising only 10-15% of all renal cell carcinoma cases. The majority of cases occur in the sixth decade of life. PRCC rarely occurs before the fourth decade in the absence of family history. This paper describes an aggressive, sporadic case of PRCC in a 20-year-old female without family history and no risk factors. CASE REPORT: A 20-year-old African American female was admitted for hemoptysis with elevated blood pressure and was found to have left peri-hilar opacification on chest X-ray. Further radiological studies led to the discovery of a large complex left renal lesion within the collecting system, infiltrating the renal artery and causing severe hydronephrosis with para-aortic lymphadenopathy. An MRI also showed signal heterogeneity in the L2 and L3 vertebrae. Biopsies of the left renal mass and a right endobronchial lesion confirmed metastatic PRCC. Treatment was commenced with a tyrosine kinase inhibitor. Within a few weeks, the vertebral metastatic lesions progressed to cause spinal compression. After targeted radiotherapy, the patient was referred to Memorial Sloan Kettering Cancer Center for enrolment in a clinical trial. CONCLUSIONS: PRCC rarely occurs in the second decade of life and even then, most such early cases occur in family clusters. PRCC also has a relatively benign course, constituting less than 10% of all metastatic renal cell carcinomas, further making this case a unique presentation.
