Odontogenic fibroma (OF) is considered an unusual, benign mesenchymal neoplasm and one of the most little-understood lesions amongst all odontogenic neoplasms. The incidence rate of the tumor is from 0% to 5.5%. WHO classified them into intraosseous or central and extraosseous or peripheral variants. It chiefly consists of fibroblastic tissue with an inconsistent amount of inactive appearing od...

Warthin's tumor is the second most common benign neoplasm of the parotid. Most of cases are represented by a single localization, while only a small percentage of patients presents bilateral lesions or unilateral multifocal pattern. Warthin's tumor has an excellent prognosis due to the low rate of recurrence after surgical treatment. Malignant transformation occurs in less than 1% of cases. The...

Background Squamous-cell carcinoma arising in a pilonidal sinus is a rare complication of a common disease. More than 60 cases are reported in literature. In all patients, squamous carcinoma arises in a long-term pilonidal disease. The gold-standard for treatment is radical excision of the neoplasm, with tumour-free margins. Some Authors consider the effectiveness of postoperative chemoor radio...

Solitary fibrous tumor (SFT) is an uncommon mesenchymal neoplasm that arises primarily from the pleura, but recognized also in other tissues. SFT in the thyroid gland is extremely rare. Here we presented the second reported SFT arising in an intrathoracic goiter. The88-year-old woman was referred with a huge goiter involving upper mediastinum accompanied by airway obstruction and tracheostomy. ...

Basal cell carcinoma is a malignant epithelial neoplasm of the skin and most common human cancer. It generally associated with good prognosis. In this case report, giant basal nodulo-ulcerative type showing wide ulceration marginal multiple small nodules, presented. was trapezoidal in shape, having dimensions 7 cm at greatest width, 6 vertically different anterior posterior margin dimensions, 5...

Microcystic adnexal carcinoma is an uncommon type of cutaneous neoplasm known by its slow growth but local aggressivity and no potential systemic metastasis. The standard diagnostic approach histopathological study a deep incisional or excisional biopsy. literature has detailed variety treatment modalities, including the Mohs micrographic surgery, excision, radiation therapy, chemotherapy, obse...

Merkel cell carcinoma is an extremely rare neuroendocrine neoplasm of the external auditory canal (EAC) skin, which requires wide excision and adjuvant radiation due to a high recurrence rate. In this report, we describe case arising from EAC was successfully treated with endoscopic excision. A 32-years-old female patient history papillary thyroid cancer diagnosed tumor incidentally. There eryt...

Malignant melanoma (MM) is the most fatal cutaneous neoplasm. Primary MM of the lung is quite rare, and late recurrence of MM is also uncommon. We report 2 cases of pulmonary MM, the first involving primary MM of the lung and the second involving late recurrence 8 years after the initial surgery. Bronchoscopic punch biopsy identified MM in both cases. In the first case, work-up of the patient d...

Aggressive angiomyxoma (AA) is a rare, slow-growing mesenchymal neoplasm of vulvo-perineal region. Although AA is common in females of reproductive age, only a few cases during pregnancy have been documented in the English literature. It carries a high risk of local recurrence but rarely metastasizes. The high recurrence rate can partially be due to inadequate excision, which may be due to an i...

A benign bone neoplasm known as an osseous fibroma is frequently referred fibro-osseous lesion. It has a stronger preference for females and thought to have originated from periodontal membrane. Maxilla less often afflicted than the mandible. This made up of highly cellular, fibrous tissue with varied levels calcified tissue, which may resemble cementum, bone, or both. Depending on degree calci...
