A 57 year old male patient presented to our hospital with vomiting, epigastric discomfort, and loss of appetite over a 24hr period. Subsequent investigations demonstrated a submucosal lesion causing gastric outlet obstruction. The patients deteriorating condition mandated laparotomy and a pathologic diagnosis was made of a pyloric submucosal fibroepithelial lesion from the resected distal stoma...

A patient who had had a lobectomy for a large cavitary lung mass died one month later. An autopsy was performed and pathologic review of surgical and postmortem specimens confirmed that the original lung lesion was metastatic hepatoma. Excavating solitary metastases from primary adenocarcinomas represent the rarest form of cavitary metastatic lesion, and this is the first report of hepatocellul...

Herein we present five cases of submasseteric abscess that most commonly occurred in patients with a history dental disease. CT has been the main imaging method for diagnosing lesions in the masticator space and adjacent to the mandible; however, we found that, in some of our cases, CT defined the lesion poorly or not at all. In some cases, MR imaging defined the lesion better. Radiologic manif...

Primary cartilaginous lesions of the larynx are relatively uncommon. We present a case of bilaterally pseudocystic lesion of the thyroid cartilage that demonstrated progressive calcification. Pathologic analysis showed features suggesting a dystrophic lesion with no evidence of malignancy. We hypothesize that repetitive microtrauma related to muscular overuse probably led to inflammatory change...

We report a case of a 70-year-old man diagnosed with a respiratory epithelial adenomatoid hamartoma (REAH) of the nasal cavity after a past sinus surgery and associated with nasal polyposis. REAH is a recently described pathologic entity that can present with nasal obstruction, congestion, rhinorrhea, epistaxis, hyposmia, and headaches. It is a rare lesion of nasal and paranasal sinuses, but sh...

Basal cell carcinoma is the most commonly seen nonmelanoma skin cancer which is rarely encountered in the childhood period. An 11-year old child was admitted to our clinic due to an erythematous and a slightly pigmented lesion with a 3 × 4 cm diameter on his posterior scalp. Macroscopically, the lesion was excised with a 10 mm safety margin. Pathologic examination revealed a basal cell carcinom...

Antegrade transmalleolar drilling method is one of the options for the treatment of osteochondral lesion of talus (OLT). We present five patients who underwent tibial drilling for treatment of OLT and later developed distal tibial cystic formation induced by cartilage opening or heat necrosis during drilling. Antegrade transmalleolar drilling can be a possible option for the treatment of OLT if...

Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's tumor, is a rare vascular lesion characterized by intravascular proliferation of endothelial-lined papillae and a propensity for manifestation in the head and neck. Signs and symptoms associated with IPEH generally occur due to compressive effects of the lesion on adjacent structures. A rare instance of IPEH occurrin...
