The interdural hematoma: A subtype of convexity subdural/dural hematoma with specific radioanatomical characteristics.

Background: Rare cases of biconvex hematomas splitting the convexity dura mater were reported and denominated interdural hematoma (IDH). Due to their rarity, little is known about their radiological characteristics, and in most cases, their invasive management with craniotomy and dural membrane excision is unnecessary.

Case Description: We report here a case of single burr-hole endoscopic evacuation of an IDH and its complete resolution after the 6-month follow-up imaging.

Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia: A Case Report and Review of the Literature.

BACKGROUND Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare pulmonary disorder that is characterized by diffuse hyperplasia of bronchiolar and bronchial pulmonary neuroendocrine cells. In this condition, when no other pathological pulmonary condition is detected, DIPNECH is considered to be an idiopathic lung disease. DIPNECH is a rare condition that can be difficult to distinguish from other forms of reactive pulmonary neuroendocrine cell hyperplasia (NECH).

Intramammary metastatic melanoma of unknown primary origin in a 58-year old patient: a case report.

Background: Malignant melanoma metastasis to the breast is a rare disease.

Case Presentation: We present the case of a 58-year-old postmenopausal Caucasian woman with metastatic malignant melanoma of unknown origin of the right breast. She presented with a palpable lump in the inferior quadrant of her right breast.

Solitary fibrous tumour with intramedullary component: case report and review of the literature.

Solitary fibrous tumours (SFTs) are rare WHO grade I mesenchymal neoplasms that were first described in the visceral pleura. A wide variety of locations of SFT have been reported but only twelve cases of intramedullary solitary fibrous tumour. We report a case of thoracic spinal cord SFT.

Primary malignant achromic melanoma of the lung.

Currently, less than thirty cases of primary malignant melanoma of the lung have been reported in the literature. Thus, strict criteria for diagnosis have been published and include: malignant melanoma associated with bronchial epithelial changes; a solitary lung tumor; no prior history of skin, mucous membrane, intestinal or ocular melanoma; and absence of any other detectable tumor at the time of diagnosis. In this article we present a case of melanoma of the lung without evidence of extra-pulmonary disease.
