1/265. A glomus tumour with four recurrences.

    A case of a glomus tumour of the distal segment of the ring finger, with four apparent recurrences in an 8-year period, is described. The patient was treated by two different surgeons (two and three times respectively) and obtained pain free intervals of between 4 and 11 months before recurrence. Histological examination confirmed the diagnosis of a glomus tumour in all five procedures. The location of the glomus tumour was defined preoperatively by high resolution MR imaging.

2/265. Histochemical investigation into the molecular mechanisms of malignant transformation in a benign glomus tumour.

    A glomangiosarcoma arose in a benign glomus tumour. The histological and immunohistochemical characteristics of the tumour were investigated. Apoptotic cells were identified by terminal deoxynucleotidyl transferase (TdT) mediated dUTP-biotin nick end labelling (TUNEL). The proportion of apoptotic cells was found to be low and TUNEL positive nuclei were present in the benign part of the tumour. Bcl-2 protein, an inhibitor of apoptosis, was strongly expressed in the glomangiosarcoma with only weak staining in the benign area. The proliferation index of the glomangiosarcoma was almost 10-fold higher than that of the benign glomus tumour. Numerous nuclei in the glomangiosarcoma were intensely stained for the tumour suppressor protein p53. The results of the this study may contribute to an understanding of the molecular basis of malignant transformation in benign glomus tumours.

3/265. Giant congenital multiple patch-like glomus tumors.

    Glomus tumors can be classified into solitary and multiple glomus tumors. Congenital multiple glomus tumors are extremely rare, and only 12 cases have been reported in the world literature. We describe the first case with giant congenital multiple patch-like glomus tumors that show partial atrophy.

4/265. Large intrapetrous facial schwannoma presenting as a glomus tumor.

    A 45 y old man suffered since a long time from right-sided hearing loss, tinnitus and, very recently, facial palsy. CT-scanning and MRI showed a very large intrapetrous lesion centered on the jugular foramen suggestive for a glomus tumor. During surgery a facial schwannoma was disclosed. The management and therapy of this lesion is discussed.

5/265. An unusual case of multiple recurrence of a glomangioma.

    Glomus tumour is a benign lesion arising from the glomus apparatus of the skin and subcutaneous tissue. Glomangioma is the angiomatous variant, which is uncommon. We report a very rare presentation of a glomangioma with multiple recurrences. We advocate preoperative angiography to delineate the extent of the lesion to facilitate complete excision.

6/265. A case of multiple subungual glomus tumors associated with neurofibromatosis type 1.

    glomus tumor is a distinctive neoplasm characterized by the presence of cells that resemble the modified smooth muscle cells of the normal glomus body, which is a specialized form of arteriovenous anastomosis. We report a case of multiple subungual glomus tumors associated with neurofibromatosis and review the literature on the pathophysiology of this association.

7/265. Multiple glomus tumor: a case report and review of the literature.

    Multiple glomus tumors are extremely rare and differ from the more common solitary glomus tumors in their clinical presentation and histological features. The authors report a case of multiple glomus tumors of the right hand in a 65-year-old man, its treatment, and a review of the features of this uncommon tumor. The tumor usually presents as a painful, firm, purplish, solitary nodule of the extremities, especially in the nail bed. Multiple glomus tumors are described as softer, more compressible, bluish nodules and they occur with less frequency than solitary tumors. They are often inherited in an autosomal dominant pattern. The authors present a case of multiple glomus tumors of the right hand, in which many small, painful, red papules were grouped in the right hypothenar region. The patient was treated by wide excision of the lesion and coverage of the defect with an ulnar artery forearm flap.

8/265. Supraclavicular glomus tumor, 20 year history of undiagnosed shoulder pain: a case report.

    A long-standing case of severe dysesthesia due to a supraclavicular glomus tumor is presented. chronic pain caused by a subcutaneous glomus (non-chemodectoma) tumor is rare and usually misdiagnosed. The supraclavicular location, presentation, and coincidence of trauma history are unique in this case. A 62-year-old male complained of 20 years of intractable right shoulder and supraclavicular region pain, which started 6 months after a fall. The pain was unrelieved by repeated and extensive physical therapy, chiropractic manipulation, local steroid injections, and two shoulder operations. The cause of the condition remained undiagnosed and obscure. Local surgical exploration revealed a subcutaneous grayish mass with pathologically proven glomus tumor. Immediate alleviation of the pain and tenderness followed complete resection of the mass. The patient remained free of pain at a 2-year follow-up. Subcutaneous glomus (non-chemodectoma) tumors can occur in unusual sites, and should be considered in chronic regional pain syndromes. Immediate cure is generally achieved by local resection. Pertinent literature is reviewed.

9/265. Congenital multiple plaque-like glomangiomyoma.

    Congenital glomus tumor is a rare clinical variant of glomus tumor, and glomangiomyoma is the least frequent histologic type of glomus tumor. We report a case of congenital multiple plaque-like glomangiomyoma in a 38-year-old man with multiple nodules and plaques on his left arm and forearm. Histopathologic study showed an angiomatous, nonencapsulated tumor with numerous highly folded dilated vascular lumina scattered throughout the dermis. The lumina were lined by a single layer of flat endothelial cells, and one to several rows of glomus cells were observed adjacent to the endothelial cells. Around large vessels, there was a gradual transition from glomus cells to elongated mature smooth muscle cells with thin and long "blunt-ended" nuclei. Immunohistochemically, there were strong positive reactions for cytoplasmic alpha-smooth muscle actin in glomus cells and smooth muscle cells, vimentin in glomus cells and endothelial cells, and desmin in the smooth muscle cells only. To our knowledge, this is the first case report of congenital multiple plaque-like glomus tumor with the microscopic appearance of a glomangiomyoma.

10/265. Solitary glomus tumour.

    A 42-year-old woman developed a purplish, tender nodule on her wrist of 6 months duration. Histological examination showed a well-circumscribed lesion situated in the dermis and subcutis characterized by numerous, dilated thin-walled vascular spaces surrounded by sheets of glomus cells. The histological findings are characteristic of the diagnosis of an uncommon type of glomus tumour, known as glomangioma.
