Lymphoid papillary hyperplasia of tonsil is a rare entity with a clinical impression of both a benign and a malignant tumor. We are reporting a case of four and a half years old Indian male child who underwent tonsillectomy for left sided tonsillar growth. Histopathologic study of the specimen showed a distinct form of lymphoid hyperplasia with finger-like projections that composed of remarkabl...

Lymphoid papillary hyperplasia is a rare abnormality of the tonsils with a predilection for affecting young Asian girls. Herein, we report a 31-year-old Chinese woman presented as right lateral recurrent tonsillar hypertrophy with odynophagia and dysphagia over the past 5 years, worsening over a period of for half a year. Clinically, this lesion was similar to papillomatosis or lymphoid polypos...

Verruco-papillary lesions (VPLs) of the oral cavity described in the literature involve a spectrum of conditions including squamous papilloma, verruca vulgaris, focal epithelial hyperplasia, condyloma, proliferative verrucous leukoplakia and verrucous carcinoma. A majority of the VPLs are slow growing, benign in nature and have a viral aetiology. Virus associated benign mucosal outgrowths are ...

BACKGROUND Intravascular papillary endothelial hyperplasia (IPEH), also known as masson tumour, is a lesion composed of proliferating endothelial cells. CASE REPORT In this article we explained clinical, histological and radiological features of IPEH involving the scalp, localized on the left side of the skull and in the periauricular region. CONCLUSIONS Radiologically, intravascular papill...

In 1923 Masson described a neo-plastic process consisting of papillary hyperplasia of the vascular endothelial cells, with a consequent obliteration of the vascular lumen, followed by degenerative changes. He introduced the term ‘vegetant intravascular hemangioendothelioma’. However, these days it is more commonly known as papillary endothelial hyperplasia (PEH) [1]. Although relatively rare, t...
