Keratoacanthoma (KA) is a self-limited benign epithelial proliferative lesion that eventually presents with very similar clinical features to squamous cell carcinoma. Many KA appear in the vermilion border of the lips and therefore dental professionals must be familiar of the disease. This article reports the case of a 40-year-old female patient presenting with an exophytic ulcerative tumor in ...

There is little information regarding flow cytometric DNA analyses of benign breast lesions. This prospective study consists of mammographic and pathological correlation of DNA flow cytometric analyses of specimen mammography-guided fine-needle aspirates (FNAs) of 189 consecutive benign breast lesions and 114 FNAs of adjacent normal tissue as a control. Clinical follow-up was also performed. An...

This report documents the bilateral presentation of oral mucous extravasation cysts on the left mucobuccal fold and right buccal mucosa of a neonate. The lesions were noted at birth and subsequently enlarged to the point that they interfered with eating. The left lesion ruptured but persisted as an exophytic fibrotic mass. Both lesions were surgically removed at eight months and the diagnosis w...

relatively unchanged over the last 10 years. Exophytic lesions are typically shaven, while deeper processes are sampled with a punch biopsy. However, we have found that these two techniques are often impractical and cumbersome in their application to some cutaneous morphologies.We introduce a technique which employs a punch biopsy-pen to perform a shave or “scoop” excision. This method is ideal...

Ameloblastic fibrosarcoma is an uncommon odontogenic tumor composed of a benign epithelial component and a malignant ectomesenchymal component most frequently seen in the third and fourth decades of life. It mainly presents as a painful maxillary or mandibular swelling. Radiographs show a radiolucent mass with ill-defined borders. Radical surgical excision and long-term follow-up are the sugges...

Tracheal botryomycosis has never been reported in the literature. A 68 year old man presented with progressive dyspnoea and an exophytic mass below the vocal cords was found by bronchoscopy. Pathological study of the mass showed tracheal botryomycosis probably associated with Peptostreptococcus spp infection. The patient was given intravenous penicillin for six weeks. Tracheal obstruction neces...

RCC: renal cell carcinoma INTRODUCTION Approximately 60,000 new diagnoses of renal cell carcinoma (RCC) are made per year, accounting for 90% to 95% of all malignant neoplasms arising from the kidney with an estimated mortality rate of 20%. Rarely, advanced RCC may exhibit cutaneous metastases, most often to the scalp, chest, arms, and fingers. We discuss an unusual case of cutaneous metastatic...

Cartilaginous tumors make up the second largest group of bone neoplasms. These are common in the long bones of the body. Chondromas among them are mostly painless, intraosseous lesions with presence at both endosteal and periosteal location. They are relatively rare in jaws owing to their membranous development and are reported to occur in cartilage bearing areas of jaws. This article is aimed ...

OBJECTIVE Apparent diffusion coefficient (ADC) values calculated through magnetic resonance imaging have been proposed as a useful tool to distinguish benign from malignant liver lesions. Most studies however included simple cysts in their analysis. Liver cysts are easy to diagnose, have very high ADC values and their inclusion facilitates differentiation in the ADC values between benign and ma...
