A 19-year-old man presented with a 5-year history of back pain radiating to the lower extremities and paresthesis of the toes during the last year. Plain X-ray revealed a large cauliflower shaped exophytic mass at the level of T8, T9 and T10 vertebrae. Computed tomography (CT) and magnetic resonance imaging (MRI) showed an abnormal bony mass arising from the posterior arch of T9 with protrusion...

Pyogenic granuloma is defined as a benign neoplasm of vascular phenotype. This case describes the clinical and histopathological features of a gigantic mucogingival pyogenic granuloma, in a 14-year-old healthy black boy. This exophytic gray-purple mass, related to a toothpick injury, had more than twelve-month evolution on the anterior mandible involving lingual area besides to the floor of the...

Nevus sebaceus can give rise to multiple neoplasms, some of which have the potential to become malignant. We describe the occurrence of a previously unreported combination of a cutaneous horn proliferating from a trichilemmoma overlying a multilocular pilar cyst and nevus sebaceus. An elderly woman with a several years’ history of multiple scalp subcutaneous nodules and an enlarging cutaneous h...

Phyllodes tumor of the breast is an uncommonly encountered disease. The tumor presenting as fungating breast mass or 'ruptured' breast is an even more rare presentation of an unusual disease. This report documents the case of a 60-year-old female with delayed presentation of a large exophytic mass of the left breast. Biopsy of this lesion was non-diagnostic, so excision via left total mastectom...

We report the case of a 67-year-old female patient who had hypertension and diabetes and had recently been diagnosed with a right renal mass. Abdominal CT and magnetic resonance imaging (MRI) showed that the renal mass, which measured approximately 7.5 cm along its longest axis, was predominantly exophytic, was located in the upper half of the right kidney, and had areas suggestive of intratumo...

Malignant epithelioid hemangioendothelioma (MEH), also known as high-risk epithelioid hemangioendothelioma, is a low- to intermediate-grade vascular malignancy originally described as a vascular neoplasm of endothelial origin. This very rare vascular neoplasm has been described mainly in soft tissue, but also in various organs and locations, including the liver, lung, brain, colon, lymph nodes,...

Around 90% of nonmelanoma skin cancers arise on the head and neck and about 10% of these occur in the area of the eyelids. Surgery continues to be the treatment of choice, but concerns about the risk of postoperative complications, local recurrence, or a poor cosmetic and functional outcome have led to the investigation of alternative options, such as cryotherapy, radiation therapy, chemotherap...

Gliosarcoma (GS) is a rare and exceedingly malignant neoplasm of the central nervous system. It displays clinical features similar to glioblastoma, yet is histologically unique as it harbors both gliomatous and sarcomatous cellular components. Involvement of the neuro-axis is predominantly limited to the cerebral parenchyma and meninges. Primary GS of the spinal cord is rarely encountered. We r...

Benign oropharyngeal tumors are far less common compared to malignant tumors. Oropharyngeal papilloma is present in adults. Squamous papillomas are exophytic masses of oral cavity. When they occur on the palate they are most often asymptomatic and benign. Pedunculated squamous papillomas usually arise from the soft palate, tonsil, or the epiglottis. These lesions can sometimes prove to be fatal...

Angiomyolipoma is a common benign renal tumor. It is typically composed of adipose tissue and hence is easily diagnosed by using imaging methods such as ultrasonography, computed tomography, and magnetic resonance imaging. However, it is difficult to differentiate an atypical angiomyolipoma such as a fat-poor angiomyolipoma from a malignant tumor by using these imaging methods. We report a case...
