What is carcinoma cuniculatum?

What is carcinoma cuniculatum?

Carcinoma cuniculatum is a rare variant of SCC, first described in 1954 by Aird et al. [4] on the foot. It is a low-grade verrucous carcinoma with a deceptive aspect of normal cell maturation. It has an endophytic burrowing growth pattern.

What is oral florid papillomatosis?

Oral florid papillomatosis is a type of verrucous carcinoma (VC) that is clinically evident as multiple squamous papillary nodules in the oral cavity and, less commonly, in the larynx, the pharynx, the esophagus, the middle ear, the maxillary antrum, the nasal fossa, and the bronchus.

What is a florid papillomatosis?

Florid papillomatosis (FP) of the nipple, or nipple adenoma, is a rare benign proliferative lesion originating from the lactiferous ducts of the nipple. It most commonly affects women in their fourth and fifth decades of life.

How is verrucous carcinoma treated?

Recurrent verrucous carcinoma carries a relatively poor prognosis. Surgical excision and Mohs micrographic (MMS) surgery represent the treatments of choice for cutaneous verrucous carcinomas. Complete surgical resection with clear margins is recommended once the diagnosis of verrucous carcinoma has been established.

Is verrucous carcinoma painful?

The lesion was non-painful, had been present for several months and recently began to increase in size rapidly. The patient presented to our office for initial treatment and I obtained a shave biopsy at this time. The biopsy confirmed the diagnosis of verrucous carcinoma.

Should oral papillomas be removed?

Oral papillomas are painless and may be left untreated. They appear not to change in size, spread to other parts of the oral cavity, or turn into malignant tumours. If treatment is indicated then conservative surgical excision that removes the head and the base of the lesion may be performed. Recurrence is unlikely.

Is papilloma a benign tumor?

Papillomas are benign growths. This means that they do not grow aggressively and they do not spread around the body. The growths only form in certain types of tissue, although these tissues occur all over the body. Papillomas are often known as warts and verrucae when they reach the skin.

What is the difference between verrucous carcinoma and squamous cell carcinoma?

Verrucous carcinoma is a rare variant of squamous cell carcinoma, which in itself is a form of non-melanoma skin cancer. While squamous cell carcinoma can appear almost anywhere on the body, verrucous carcinoma is more localized, often appearing in specific areas.

Is verrucous carcinoma aggressive?

Verrucous carcinoma is a relatively uncommon, locally aggressive, clinically exophytic, low-grade, slow-growing, well-differentiated squamous cell carcinoma with minimal metastatic potential.

Can oral papillomas be cancerous?

HPV can infect the mouth and throat and cause cancers of the oropharynx (back of the throat, including the base of the tongue and tonsils). This is called oropharyngeal cancer. HPV is thought to cause 70% of oropharyngeal cancers in the United States.

What does an oral papilloma look like?

Oral papillomas can be recognized by their small fingerlike projections, resulting in an exophytic lesion with a rough or cauliflowerlike verrucous surface (Figure 1). These lesions often have a white appearance and can occur in any age group.
