A guinea pig (9-week-old) that had been placed in a control group for a pharmacological test was found to have a single nodule on the surface of the right ventricular wall. In a transverse section of the heart after fixation, a whitish mass was found that extended from the subendocardium to the subepicardium of the right ventricular wall. Histopathological examination revealed a spongy network ...

Birt-Hogg-Dubé (BHD) syndrome is an autosomal dominant disorder that presents with renal tumors, pulmonary cysts with spontaneous pneumothoraces, and skin hamartomas. We present a case of a 67-year-old female with multiple endocrinopathies and a history of BHD syndrome. In 2011, a thyroidectomy with a four-gland parathyroidectomy was performed for toxic multinodular goiter (TMNG) and parathyroi...

UNLABELLED Cardiac rhabdomyoma is the most common primary cardiac tumor, is considered to be a hamartoma of developing cardiac myocytes. Cardiac rhabdomyoma is associated with tuberous sclerosis complex (TSC) in 50-86% of cases. Mutations in TSC-1/TSC-2 genes result in increased mammalian target of rapamycin (mTOR) pathway activation responsible for the hamartomatous lesions of tuberous scleros...

A case of intermediate form of foetal rhabdomyoma with cytological correlation is reported in a ten-year-old girl who presented with a lump in the right neck region. Fine-needle aspirate of the lump was performed. Cytological findings were that of spindled cells and rhabdomyoblasts with abundant eosinophilic cytoplasm. The lesion was subsequently excised. Histology showed a well-circumscribed c...

Cardiac rhabdomyoma is the most common cardiac tumor in fetal life, accounting for 60-86% of primary fetal cardiac tumors. It is primarily benign, originating form myocardial muscles and consisting of immature myocytes. About 50-60% of these tumors are associated with tuberous sclerosis. In this report, we present the clinical course and discuss the importance of prenatal diagnosis of cardiac t...

Rhabdomyomas are the most common primary cardiac tumors in childhood, and are often associated with tuberous sclerosis. We report a huge rhabdomyoma in an asymptomatic four hour old infant who presented initially with a murmur due to moderate subaortic stenosis. Followup showed regression of the tumour. Although the indications for surgical resection of symptomatic tumors are well established, ...
