Atypical fibroxanthoma (AFX) is a nodular dermal ulcerative lesion with a favorable prognosis. AFX most commonly occurs on sun-exposed skin in elderly individuals. AFX is characterized by its association with ultraviolet radiation, not only from a clinical aspect, but also from a molecular aspect. Making a diagnosis of AFX is challenging, and it is important to differentiate it from squamous ce...
Primary malignant melanoma of the esophagus (PMME) is a rare disease, comprising 0.1-0.2% of all malignant esophageal neoplasms. The most common symptoms include progressive dysphagia, chest and back pain, choking feeling and weight loss. PMME cannot be definitely diagnosed from clinical symptoms or CT examination, but can be confirmed by histological examination or a pathological examination. ...
Hepatic perivascular epithelioid cell tumors (PEComas) are very rare. We report a primary hepatic PEComa with a review of the literature. A 56-year-old women presented with a nodular mass detected during the management of chronic renal failure and chronic hepatitis C.

A 39-year-old nulliparous woman became breathless after a caesarean section. CT pulmonary angiography (fig 1) showed no filling defect but cysts, small bilateral effusions and thickened interlobular septa were visible consistent with a possible diagnosis of lymphangioleiomyomatosis (LAM). An open lung biopsy performed 11 months later showed that the lung parenchyma contained scattered cysts of ...
An unusual primary adenomatoid tumour arising in the normal liver is described. Hepatectomy was performed, and the patient is alive and free of disease 1 year postsurgery. Grossly, the tumour showed a haemorrhagic cut surface with numerous microcystic structures. Histological examination revealed cystic or angiomatoid spaces of various sizes lined by cuboidal, low-columnar, or flattened epithel...
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare congenital neoplasm that originates from the neural crest cells, which give rise to the melanocytes of the skin and leptomeninges. We report a case of MNTI with neurocutaneous melanosis of a 28-month-old girl. She was born with hydrocephalus and several large congenital giant nevi. There were no findings except for hydrocephalus, after...
Clear cell sarcoma (CCS), initially named malignant melanoma of soft parts, is a rare malignant neoplasm typically involving deep soft tissue of the extremities, in close proximity to tendons and aponeuroses. Here we describe a case of clear cell sarcoma of the right parapharyngeal region in a young female aged 20 years. MRI detected a mass about 4.4 cm×3.4 cm×3.0 cm, located in the right parap...
Solitary fibrous tumor (SFT) is a rare spindle cell neoplasm that usually arising from the pleura, but has been reported in diverse extrapleural sites. Urogenital localization is rare, and only several cases of paratesticular SFT have been reported. In the present report, we present the case of a 61-year-old male suffering from a paratesticular SFT.
