1/19. lymphangioma circumscriptum of the tongue.A case is reported of severe transient macroglossia after biopsy from the tongue in a 13-year-old boy who has had intermittent macroglossia since the age of 1 year as a result of extensive lymphangioma circumscriptum of the tongue. The acute lesions appear to result from haemorrhage into the lymphatic spaces following rupture of blood vessels in connective tissue septa and possibly secondary infection.- - - - - - - - - - ranking = 1keywords = blood vessel, vessel (Clic here for more details about this article) |
2/19. Endovascular papillary angioendothelioma (Dabska tumor) of the tongue: report of a case.Endovascular papillary angioendothelioma (EPA), known as Dabska tumor, is a very rare vascular neoplasm that usually occurs in the skin or subcutis of infants and young children. There is no previous report of EPA appearing in the oral cavity. Here, we present an exceptionally rare case of EPA of the tongue in a 67-year-old man. A well-defined, reddish tumor measuring 11 mm x 8 mm x 7 mm existed at the submucosal area of the left tongue margin. Microscopic examination of an excisional biopsy specimen revealed the endothelioid tumor cells showing a papillary growth pattern, such as blood vessel-like structures. Immunohistochemical studies showed positive reactivities for CD31, CD34, alpha-smooth muscle actin, and factor viii-related antigen in most of the tumor cells and CD68 in some tumor cells. Based on these observations, the tumor was diagnosed as an EPA.- - - - - - - - - - ranking = 1keywords = blood vessel, vessel (Clic here for more details about this article) |
3/19. Spindle cell rhabdomyosarcoma of the tongue in an infant: a case report with emphasis on differential diagnosis of childhood spindle cell lesions.Malignant tumors are extremely uncommon in infants, specifically in the head and neck region. We present a three-day-old infant with a large, polypoid, soft tissue mass arising from the floor of the mouth. Histologically, this neoplasm consisted of hypercellular and myxoid areas. A mixture of poorly oriented, small, undifferentiated, hyperchromatic, and round to elongate spindle cells was seen. A high degree of striated muscle differentiation was present, along with areas marked by a herringbone pattern, as well as hemangiopericytic vessels and rare mitosis. Immunohistochemical examinations revealed strong nuclear staining for myogenin and diffuse cytoplasmic staining for desmin and muscle-specific actin (HHF-35). The tumor did not stain for S-100. Based on histologic results and immunostains, this lesion was diagnosed as spindle cell rhabdomyosarcoma. This type of lesion involving the tongue is rarely seen in females, neither in association with a herringbone pattern nor with hemangiopericytic vessels. Furthermore, rare benign and malignant spindle lesions, such as cellular fibromatosis, fetal rhabdomyoma, infantile hemangiopericytoma, infantile rhabdomyofibrosarcoma, and infantile fibrosarcoma, should be in the differential diagnosis and excluded.- - - - - - - - - - ranking = 0.2667210949051keywords = vessel (Clic here for more details about this article) |
4/19. Aspiration cytology of pulmonary small cell variant of poorly differentiated synovial sarcoma metastatic from the tongue: a case report.BACKGROUND: Small cell variant ofpoorly differentiated synovial sarcoma (PDSS) is a great mimic of Ewing's sarcoma/primitive neuroectodermal tumor, with cytologic and immunohistochemical overlap. CASE: A 21-year-old male was admitted to our hospital because of a solitary pulmonary nodule that developed 22 months after resection of a tongue mass, small cell variant of PDSS. The nodule was biopsied via fluoroscopy-guided fine needle aspiration (FNA). At low power, the cytologic smears were highly cellular, consisting of a mixture of dispersed cells and loose or tight tissue fragments. The cells were characteristically uniform and monotonous, showing round to ovoid nuclei and scant cytoplasm. However, at high power, mild nuclear pleomorphism and frequent mitotic figures were noted. blood vessels were often seen within the tumor cell aggregates. A diagnosis of metastatic sarcoma was rendered. Metastatectomy of the lung nodule was performed, and cytogenetic study showed t(X;18). CONCLUSION: A diagnosis of small cell variant of PDSS is difficult on routinely stained smears, but in the appropriate clinical setting, especially when a prior history of a primary tumor is available, a confident diagnosis can be established by FNA cytology. immunohistochemistry and identification of SYT/SSX fusion transcript are useful for confirmation.- - - - - - - - - - ranking = 0.13336054745255keywords = vessel (Clic here for more details about this article) |
5/19. Proximal forearm flap based on a septocutaneous vessel from the radial artery.BACKGROUND: The radial forearm flap has been a workhorse flap for soft-tissue or coverage reconstruction in the head and neck area. Although it has several major advantages, it requires sacrifice of the radial artery. In this article, the authors present their modification of harvesting a forearm flap based on a large septocutaneous branch of the radial artery in the proximal forearm with or without sacrificing the main radial artery. They name it the proximal radial forearm flap. methods: From September of 2003 to March of 2004, a total of 14 free proximal radial forearm flaps were used for head and neck reconstruction in 12 patients. There was one female patient and 11 male patients. Their ages ranged from 32 to 85 years. The skin flap size ranged from 2.0 x 6.0 cm to 4.5 x 18 cm. RESULTS: All free proximal radial forearm flap reconstructions had immediate success. There were one delayed flap loss caused by wound infection and one death attributable to advanced medical disease. Six flaps were harvested with preservation of the radial artery trunk. Six of the eight radial arteries that were killed during flap harvest were repaired with a short segment (3 to 4 cm) of vein graft. The average diameter and length of the septocutaneous vessel of the proximal radial forearm flap was 0.73 mm and 3.3 cm, respectively. Two flaps were harvested in conjunction with the conventional free radial forearm flaps. Nine donor sites were closed primarily and five donor sites required skin grafts. CONCLUSIONS: The proximal radial forearm flap can be used successfully in head and neck reconstruction with the advantages of moving the donor site to the proximal forearm for better scar concealment and possible preservation of the radial artery trunk. The disadvantages of this flap are short pedicle length and small pedicle diameter when the radial artery is to be preserved.- - - - - - - - - - ranking = 0.66680273726274keywords = vessel (Clic here for more details about this article) |
6/19. angiokeratoma of tongue: a series of 14 cases.Angiokeratomas (AC) are vascular lesions which are defined histologically as one or more dilated blood vessels lying directly subepidermal and showing an epidermal proliferative reaction with ectatic capillaries in the papillary dermis. Only three other cases of isolated mucosal angiokeratoma have been reported in the indexed literature. We reviewed all cases of angiokeratoma located on the tongue, diagnosed in our department during a study period of 10 years (1995-2005). Histologically all 14 cases showed dilated and congested blood vessels in the upper papillary dermis. They lack deep dermal involvement. Hyperkeratosis and acanthosis were also seen in most of the cases. No clinical data was available to assess systemic disease. A higher incidence of of AC in tongue is seen in our study.- - - - - - - - - - ranking = 2keywords = blood vessel, vessel (Clic here for more details about this article) |
7/19. Benign mesenchymoma of the tongue. Report of a case, with review of the literature.A benign mesenchymoma of the dorsal midtongue in an 88-year-old woman is presented. The tumour was excised under local anaesthesia, and microscopic examination revealed cartilage, bone, striated muscle, peripheral nerve, adipose and myxoid tissue, and blood vessels in addition to fibrous tissue. Eight cases including ours were found in the literature.- - - - - - - - - - ranking = 1keywords = blood vessel, vessel (Clic here for more details about this article) |
8/19. glycogen-rich clear cell carcinoma in the tongue. A cytochemical and ultrastructural study.An unusual epithelial neoplasm arising in the tongue of a 17 month-old-boy was studied by light and electron microscopy. By routine light microscopic examination, the tumor cells exhibited clear cytoplasm. Histochemical studies revealed the presence of large amounts of periodic acid-Schiff (PAS)-positive, diastase-labile material in the cytoplasm. Ultrastructurally, this material was identified as electron dense particles (20-35 nm diameter) of beta-glycogen. The epithelial nature of the tumor cells was suggested by the presence of intercellular junctions, segments of basal lamina, and well-developed Golgi complexes. Furthermore, the cells were often clustered and formed abnormal lumina with small microvillus projections. Several histologic features, such as lack of capsule, infiltration of muscle and invasion of blood vessel, indicated that this neoplasm was malignant. However, there was no recurrence or distant metastases more than 2.5 years after surgical excision, suggesting a low-grade malignancy. The glycogen-rich clear cell variant of adenocarcinoma is histogenetically derived from minor salivary glands like most of the glandular neoplasms in the oral cavity. Investigation of the literature on adult and childhood minor salivary gland neoplasms revealed that the glycogen-rich, clear-cell variant of adenocarcinoma has not previously been reported in the tongue.- - - - - - - - - - ranking = 1keywords = blood vessel, vessel (Clic here for more details about this article) |
9/19. lymphangioma of the tongue: report of case.Lymphangiomas are benign tumors of the lymphatic vessels, usually found in children. Lymphangiomas, however, may be misdiagnosed and in the absence of treatment may increase in size, producing macroglossia, swallowing and speech interferences, and respiratory difficulty. The size and isolated location of the lesion in the midline of the tongue reported here are unusual; few similar cases have been reported in the literature. Complete surgical excision provided not only removal of the lesion, but allowed normal recontouring of the tongue.- - - - - - - - - - ranking = 0.13336054745255keywords = vessel (Clic here for more details about this article) |
10/19. Metastasis to the lingual lymph node in carcinoma of the tongue.Lingual lymph nodes are occasionally found along the course of some lymph-vessels of the tongue. However, their existence has received little attention and metastasis of carcinoma of the tongue to them has not previously been reported. Three cases of carcinoma of the tongue with metastasis to the lingual lymph node are described and a discussion of the importance of such metastasis in the treatment of carcinoma of the tongue is presented.- - - - - - - - - - ranking = 0.13336054745255keywords = vessel (Clic here for more details about this article) |
