Hamartoma of the esophagus is a rare lesion and the number of cases reported in the literature to date is limited. The majority of hamartomas are intraluminal tumors located in the upper third of the esophagus. Histopathologically, the majority of these tumors comprise a mixture of adipose tissue, skeletal/smooth muscle tissue, vascular components and fibrous connective tissue. We herein presen...

Hamartomas are the most common benign tumors of the lung. Endobnronchial hamartomas are even rarer and infrequently causes hemoptysis. We report a case of endobronchial hamartoma that was originating from a segment bronchus and invisible in chest X-ray. A 63-year-old man was admitted to hospital with hemoptysis. A CT scan revealed endobronchial mass obstructing anterior bronchus of the right lo...

Angiomyomatous hamartoma is a rare tumour of lymph nodes. This report describes a case of angiomyomatous hamartoma in the inguinal lymph node. The patient was a 33-year-old woman who underwent surgery because of a right inguinal mass. The excised specimen consisted of a grossly enlarged lymph node covered with fatty tissue, measuring 4.5 cm in diameter. On microscopic examination, the lymph nod...

INTRODUCTION Pulmonary hamartoma is a rare benign tumor of the lung, accounting for 3% of all tumors of the lung (1). The term hamartoma was first introduced by Albrecht in 1904 to describe tumor-like malformations resulting from a presumptive development abnormality. In 1934, Goldsworthy applied this term to benign tumors located in the lung that were predominantly composed of a combination of...

Acquired scrotal giant muscular hamartoma is an uncommon benign lesion with fewer than 10 documented cases all over the world. It is characterized by a proliferation of dermal smooth muscle bundles of scrotum dartos fascia. The authors report a rare case of acquired scrotal giant muscular hamartoma, which occurred in a 70-year-old severely obese and diabetic man presenting with a progressive sc...

Brunner's gland hamartomas are small benign lesions that are most commonly found in the bulb of the duodenum. They are very uncommon, and most are found incidentally during upper gastrointestinal series or esophagogastroduodenoscopy. The lesions tend to be asymptomatic, but patients may present with symptoms of duodenal obstruction or hemorrhage secondary to ulceration. Histologically, a Brunne...

Neural fibrolipomatous hamartoma is a rare benign tumour commonly involving the median nerve. Other less frequently involved nerves include the ulnar, radial, brachial plexus, superficial peroneal nerve, inferior calcaneal nerve and median plantar nerve. Involvement of sural nerve has not been reported in the available literature so far. A three-year-old female child presented with a painless s...

BACKGROUND Fibrous hamartoma of infancy (FHI) is an infrequent benign proliferation of the soft tissues. Ninety one percent of cases occur during the first year of life. FHI is characterized as a subcutaneous lesion with characteristic morphology with a triphasic organoid growth pattern. CLINICAL CASE We present the case of a 6-month-old male infant with a tumor in the medial plantar region o...
