Hansen et al. (1985) described proliferative verrucous leukoplakia (PVL) as a distinct entity of leukoplakia, presenting as verrucous, or exophytic lesion with progressive histological changes in sequential biopsies such as hyperkeratosis, different grades of dysplasia, verrucous carcinoma, and squamous cell carcinoma (SCC) [1]. In 2005, the WHO defined PVL as a rare subtype of oral leukoplakia...

We report a rare case of verrucous carcinoma occurring in the nasal cavity. A 53-year-old man reporting left-sided nasal obstruction and awareness of a left intranasal lesion--a whitish polypoid lesion--was found in CT to have an expansive lesion of the left nasal cavity and maxillary sinus. The tumor was completely removed by Denker's operation. Verrucous carcinoma is a rare variant of squamou...

F ifty-year-old male smoker presented with a slowgrowing raised lesion on the mucosal surface of his upper lip (Fig. 1). He underwent an excisional biopsy and pathology confirmed verrucous hyperplasia without evidence of malignancy as shown in Fig. 2. Patient made an uneventful recovery. The most common site of presentation involves the buccal mucosa (48%) followed by the tongue (20%), palate (...

intra-tumoral bleeding, rupture and thrombosis are common complications of hemangioma but spontaneous and self limited rupture and fever is a very rare presentation of hemangioma. this report is about a 38-year-old woman with sever abdominal pain and high fever came for evaluation. in us she had a liver mass of about 15 cm in left lobe with possibility of being hemangioma and, ct scan and mri c...

Leprosy (Hansen's disease) is a chronic granulomatous disease caused by Mycobacterium leprae (Hansen's bacillus). Oral manifestations occur in 20-60% of cases, usually in lepromatous leprosy, and are well documented. They may involve both the oral hard and soft tissues. Incidence of verrucous carcinoma/Ackerman's tumour developing in anogenital region and plantar surfaces of feet in lepromatous...

We report a case of basal cell carcinoma that appeared from an epidermal verrucous nevus in a 61-year-old patient. The onset of basal cell carcinoma in sebaceous nevi, basal cell nevi and dysplastic nevi is relatively common, but it is rarely associated with epidermal verrucous nevi. There is no consensus on whether the two lesions have a common cellular origin or whether they merely represent ...

by increasing number of vessels. Salivary gland tumors are uncommon and their overall incidence is about 3 per 100000 per year. Salivary gland hemangioma makes up 1 % of all salivary gland tumors. Trismus resulting from parotid hemangioma is so rare. The patient was a 6-month-old boy with a huge lesion in his right parotid who referred to Shahid sadoughi hospital of Yazd, Iran. The lesion appea...

Verrucous lichen planus (VLP), is a chronic inflammatory dermatosis mainly involving the lower limbs. It rarely affects the perineal area, where it occurs in association with other mucocutaneous lichen lesions. We here report the case of a 51-year old patient with isolated perineal verrucous lichen planus. The patient, who had no significant medical history, presented with painless, verrucous, ...

Verrucous carcinoma of the larynx clinically resembles laryngeal papilloma in that both are wart-like masses on the vocal cords and may be characterized by multifocality and recurrence. Human papillomavirus (HPV) infection is an etiological factor in laryngeal papilloma, and recent evidence implicates HPV in squamous neoplasias. To determine whether HPV is also associated with verrucous carcino...
