Malignant melanoma involving the respiratory tract is nearly always metastatic from a cutaneous lesion. Primary malignant melanoma of the lung (PMML) is very rare. We herein report the case of a 61-year-old female patient with PMML who presented with a small nodule in the lower lobe of the left lung on chest computed tomography. As an intraoperative diagnosis of malignant melanoma was made, lef...

Plexiform schwannoma is a rare benign neoplasm of the neural sheath characterized by a multinodular plexiform growth pattern. The tumor usually occurs as an isolated finding, although rare cases have been reported in association with neurofibromatosis type 2 (NF2). A 25-year-old man was admitted for foot drop.

A 32-year-old man, with an unremarkable medical history, presented with a two-month history of an asymptomatic solitary nodule on his left cheek. Histopathological examination demonstrated a dense nodular and diffuse dermal lymphocytic infiltrate with numerous histiocytes and dendritic cells that surr...

775 Pilomatricoma is a benign skin neoplasm that arises from hair follicle matrix cells. It occurs on the head, neck, and upper extremities, and less frequently on the trunk and lower extremities. The etiology of pilomatricoma is subject to controversy. Trauma, insect bites, or surgery are thought to be antecedent events to the onset of the tumors. Influenza vaccination is a common annual event...

A 58-year-old Japanese woman presented an eruption in the region of the back and the upper extremities, a subcutaneous nodule on the right breast, and a left cervical lymphadenopathy. The excision biopsy specimens, of a subcutaneous nodule and a lymph node, showed a vaguely nodular growth pattern comprising a small CD20 IgD lymphocyte infiltrate around clusters of medium-sized or large CD3 lymp...

Cutaneous endometriosis, characterized by the presence of endometrium or endometrial-like tissue outside uterine cavity, is an uncommon and chronic disease. Depending on a patient's history, cutaneous endometriosis classified as either primary (PCE) secondary (SCE). We report case SCE presenting with classic triad previous caesarean section, subcutaneous nodules at site scar, pain associated me...

Aspergillus species are among the most ubiquitous fungi, seen in soil, water, decaying vegetations and any substrate that contains organic debris. The respiratory tract is the most common primary portal of entry. After candida albicans, the aspergillus species is the second most common cause of human opportunistic fungal infection. Our patient was taking oral corticosteroids for more than one y...
