Four patients with Fabry's disease diagnosed by right ventricular endomyocardial biopsy had cardiac manifestations simulating hypertrophic cardiomyopathy (HCM). Case 1: A 51-year-old woman, whose elder sister had congestive heart failure, was hospitalized for exertional dyspnea and cardiomegaly. Her electrocardiogram (ECG) showed a short PQ interval (0.10 sec) and left ventricular hypertrophy. Her echocardiogram (Echo) showed moderate symmetrical hypertrophy of the left ventricle (IVST/PWT = 18 mm/17 mm). Case 2: A 32-year-old woman, whose elder sister had an abnormal ECG, was hospitalized for the ECG abnormalities consisting of a short PQ interval (0.10 sec) and ST-T changes in the left precordial leads. The Echo revealed mild symmetrical hypertrophy of the left ventricle (IVST = 13 mm, PWT = 13 mm). Case 3: A 44-year-old man was hospitalized for his ECG suggestive of left ventricular hypertrophy, and his Echo showed asymmetrical septal hypertrophy (ASH; IVST = 22 mm). Case 4: A 51-year-old man was hospitalized for his ECG showing high voltage in the left precordial leads, and his Echo showed ASH (IVST = 20 mm). The cardiac histopathological findings of these cases included cytoplasmic vacuolization by light microscopy, and electron-dense deposits consisting of parallel or concentric lamellae with periodic spacing, suggesting Fabry's disease. The urinary glycolipids of Case 1 were increased biochemically; then the diagnosis of Fabry's disease was confirmed. Cardiac hypertrophy in Fabry's disease has many aspects, because the histopathological changes and clinical manifestations are determined by genetic factors. It was concluded that Fabry's disease may be concealed in some patients with the clinical diagnosis of HCM.

Hypertrophic cardiomyopathy is one of the most common causes of sudden cardiac death among young adults and adolescents. Unfortunately, the first manifestation of the condition may be sudden death during exertion, such as sporting activities. Other clinical symptoms include exertional dyspnea, angina, and syncope. Postmortem examination often reveals asymmetrical septal thickening and mural plaque formation in the left ventricular outflow tract. Histologic analysis shows cardiac myocyte hypertrophy, myofiber disarray, and interstitial and replacement fibrosis. Molecular analysis for known genetic abnormalities is essential to genetic counseling of living relatives of decedents to assess and reduce the risk of sudden cardiac death from hypertrophic cardiomyopathy.

Cryptogenic organizing pneumonia (COP) is a rare entity in childhood, particularly in previously healthy children. Moreover, the spontaneous remission of the disease is exceptional. We report on the case of a previously healthy 10-year-old girl who consulted her doctor for a 2-month history of mild pyrexia, fatigue, weight loss, and exertional dyspnea with no response to amoxicillin. A chest CT revealed bilateral, asymmetrical peribronchovascular consolidation areas predominating in the lower lobes and imaging features of COP. The bronchoalveolar lavage and the biological findings were negative. On follow-up, the girl showed clinical and radiological remission of the disease with no treatment. Our report describes an extremely rare case of spontaneously resolving COP in a child, the diagnosis being made based on the imaging pattern.

Sarcoidosis is a multisystem disorder of unknown etiology, characterized pathologically by the presence of nonnecrotizing granulomatous inflammation in affected organs. Although skeletal muscle is involved in 50-80 percent of individuals with sarcoidosis, symptomatic myopathy has been shown to be a rare manifestation of the disease. Inclusion body myositis (IBM) is a rare acquired idiopathic inflammatory myopathy with the insidious onset of asymmetric and distal muscle weakness that characteristically involves the quadriceps, tibialis anterior, and forearm flexors. Moreover, dysphagia can be the presenting complaint in one-third of patients. Herein, we are presenting a case of 67-year-old African American female who presented with one-month history of new onset progressive dyspnea on exertion. She was diagnosed with stage IV sarcoidosis based on chest CT scan findings and transbronchial lung biopsy revealing nonnecrotizing granulomatous inflammation. Over the next three months after her diagnosis, she presented to the hospital with progressive dysphagia associated with asymmetrical distal muscle weakness. A quadriceps muscle biopsy revealed features consistent with inclusion body myositis. We are reporting this case as it may support the hypothesis of sarcoidosis being a trigger that possibly promotes the development of inclusion body myositis, leading to a very poor prognosis.
