A progressive wart-like syndrome in both captive and wild populations of the Western barred bandicoot (WBB) is hindering conservation efforts to prevent the extinction of this endangered marsupial. In this study, 42 WBBs exhibiting the papillomatosis and carcinomatosis syndrome were examined. The disease was characterized by multicentric proliferative lesions involving cutaneous and mucosal sur...

Confluent and reticulated papillomatosis (CRP) of Gougerot and Carteaud was first typified in 1927. With the help of electron microscopy, it has been elucidated that CRP arises due to aberrant keratinization. However, till date, there is no clear consensus on the etiologic trigger for CRP. Prevailing postulates include a bacterial trigger by Dietzia papillomatosis (type strain N 1280(T)), an ex...

Introduction: Recurrent respiratory papillomatosis (RRP) is usually a relatively benign disease but can have an aggressive clinical course. The primary treatment for laryngeal papillomatosis is endoscopic resection. However, there is no effective treatment for pulmonary spread of laryngeal papillomatosis. Case Presentation: We describe a rare case of a 19-year-old man with pulmonary spread of l...

Conservation efforts to prevent the extinction of the endangered western barred bandicoot (Perameles bougainville) are currently hindered by a progressively debilitating cutaneous and mucocutaneous papillomatosis and carcinomatosis syndrome observed in captive and wild populations. In this study, we detected a novel virus, designated the bandicoot papillomatosis carcinomatosis virus type 1 (BPC...

* Correspondence: [email protected] Bovine papillomatosis (BP) is distributed worldwide among cattle but is relatively less common in buffaloes. Prevalence of this disease is established in buffaloes from India (1,2) and Italy (3) caused by bovine papilloma virus (BPV). BPV is a nonenveloped double stranded DNA virus with icosahedral symmetry that infects the cutaneous and mucosal epithel...

Esophageal papillomatosis is a very rare condition that is believed to have a benign clinical course. Recent reports underscore the potential development of a malignancy in association with squamous papillomatosis of the esophagus. A case of esophageal papillomatosis complicated by the development of esophageal invasive squamous cell carcinoma diagnosed after esophagectomy, despite multiple non...

Papillomatosis is a relatively common (22%) benign microscopic lesion in the breast and rarely seen in women less than 30 years old. It is a papillary proliferation of the ductal epithelium which partly fills up smaller ducts and to degree distends them. The histological classification of this entity is controversial because similar or identical lesions have been classified using different term...

Papillary lesions of breast represent a range of lesions. Intraductal papilloma and its association with nipple discharge are well known. However, multiple papillomatosis has quite distinct characteristics and decision making can be somewhat challenging. We report a case of multiple papillomatosis in association with ductal carcinoma in situ (DCIS). Patient opted for ipsilateral mastectomy and ...

A 55-year-old male developed itching on the anterior aspects of both legs and the right ankle. Gradually over the next 5 years there was thickening of the skin on these areas followed by the appearance of hyperpigmented, scaly, severely itchy plaques. He also noticed the appearance of a thick, hard horn-like structure projecting from the surface of the right ankle lesion for the last 2 years. A...

BACKGROUND Co-infection of leishmaniasis and HIV is increasingly reported. The clinical presentation of leishmaniasis is determined by the host immune response to the parasite; as a consequence, this presentation will be influenced by HIV-induced immunosuppression. As leishmaniasis commonly affects the skin, increasing immunosuppression changes the clinical presentation, such as in post-kala-az...
