Solitary oral plexiform neurofibroma: review of literature and report of a case

Plexiform neurofibroma (PN) is a rare, benign tumor of nerve sheath origin, which frequently manifests as part of neurofibromatosis type 1. The article presents a case of solitary PN in a 4-year-old girl, which manifested as a double lip and without systemic or familial involvement. A review of the literature on solitary PN in the oral soft tissue demonstrates the scarcity of such cases.     

Solitary gastric recurrence from ovarian carcinoma: a case report and literature review

BACKGROUND: Isolated gastric recurrence due to ovarian cancer is a rare event and is usually associated with gastrointestinal symptoms. CASE REPORT: We report a case of an isolated gastric recurrence of ovarian carcinoma in an otherwise asymptomatic 42-year-old woman in whom diagnosis was made using the FDG-PET/CT scan followed by laparoscopy. CONCLUSIONS: In rare cases, ovarian cancer can directly recur on the stomach without any symptoms. FDG-PET/CT scan and diagnostic laparoscopy are effective in leading to an early diagnosis of disease recurrence.     

Solitary splenic metastasis: case report and review of the literature

Solitary splenic lesion is a rare presentation of a previous or current malignancy. We describe a case of an isolated splenic lesion caused by endometrial carcinoma and summarize all the published reports on solitary splenic metastasis.     

Solitary intracranial plasmacytoma--a case report and review of the literature

A 49 year old man had had headache and some cranial nerve paralyses for about three years. A tentative diagnosis of meningioma of the skull base or chordoma was made before his death. In the postmortem examination, a large tumor lying on the skull base was found. The sella turcica, a part of the basilar bone were destroyed. The neoplasm had invaded the adjacent cerebrum, cranial nerves and extra-cranial tissues. Histopathologically, the lesion showed a typical poorly-differentiated plasmacytoma. Both clinic and pathologic characteristics of this tumor are discussed and the literature on solitary intracranial plasmacytoma is reviewed.     

Solitary intracranial subdural osteoma: case report and review of the literature

Intracranial subaural osteomas without any relation to osseous or meningeal tissues are rare, with only five cases including the present one having been reported so far. In most patients headache, which was always localized at the site of the lesion, was the most frequent complaint and subsided after complete resection of the neoplasm. The mechanism of origin of such lesions remains unknown.     

Solitary mastocytoma of the lung: a case report and a brief review of the literature

We report a case of a 51-year-old woman with a solitary mast cell tumor of the lung, a rare neoplasm with only three previous cases reported in the literature. Unlike the reported cases, the tumor in our observation was bulky, measuring 14 cm of diameter and budding into the segmental bronchus. Histological examination was consistent with mastocytoma and further investigations excluded the diagnosis of systemic mastocytosis. The differentiating features of this neoplasm and a review of literature are herein presented.     

Solitary fibrous tumor of small bowel mesentery: a case report and review of the literature

Solitary fibrous tumor is an extremely rare clinical entity, most commonly manifested in the pleura and peritoneum. An increasing number of cases are found to occur at extrapleural sites. We report a case of solitary fibrous tumor arising from the mesentery of the small intestine. A 53-year-old man presented with a large abdominal mass which was initially thought to be a gastrointestinal stromal tumor. The tumor was successfully removed surgically and the diagnosis of solitary fibrous tumor was confirmed on immunohistochemical analysis. To our knowledge this is the first reported case of a solitary fibrous tumor arising from the small bowel mesentery.     

Solitary Langerhans cell histiocytosis of frontal lobe: a case report and literature review

The brain parenchymal Langerhans cell histiocytosis （LCH） without systemic disease or lytic skull lesions is extremely rare. We report a 23-year-old male presenting with new onset 1 hour seizure with loss of consciousness 20 days prior to admission, and recurrent seizure 2 weeks later. Brain magnetic resonance imaging （MRI） showed an irregularly mass with enhancement involving the right frontal lobe. Microscopically, the lesion was characterized by sheets of Langerhans cells in addition to reactive inflammatory elements. Immunohistochemically, Langerhans cells were positive for Langerin, CDla and S-100 protein. The patient received no chemotherapy or radiotherapy after surgery. After 24 months of follow-up, no recurrence or other systemic lesions were observed. Although there is no standard treatment for solitary cerebral LCH, the prognosis generally appears to be good.     

Solitary extramedullary plasmacytoma of the bladder: a case report and literature

Plasmacytoma is a rare B-lymphocyte neoplastic disorder that usually presents as the generalized disease multiple myeloma. Less than 5% of the cases present as a solitary mass of monoclonal plasma cells in the bone or soft tissue. Although solitary extramedullary plasmacytoma (SEP) may arise in any organ, it rarely involves the urinary bladder. A 67-year-old male without a history of multiple myeloma presented with urinary frequency and nocturia; he was later diagnosed with SEP of the bladder. The patient was initially treated with a course of radiation therapy without symptomatic improvement; therefore a chemotherapy regimen consisting of lenalidomide and dexamethasone was subsequently given for six cycles. SEP usually carries a better prognosis and higher cure rate than solitary plasmacytoma of bone, as SEP is radiation sensitive. The role of adjuvant chemotherapy in the treatment of SEP that is resistant to radiation therapy is not clear, since most of the recommendations have been derived from the experience of head and neck SEP. The literature also lacks recommendations for choice of a chemotherapy regimen and surveillance of isolated bladder plasmacytoma. Here we present the first case of a radiation-resistant solitary plasmacytoma of the bladder that was successfully treated with lenalidomide and dexamethasone with successful clinical remission.
