11/892. Follicular carcinoma in ectopic thyroid gland. A case report.

    Ectopic thyroid rest can be seen anywhere along the path of descent of the gland. The most ectopic thyroid tissue is a thyroglossal duct cyst associated with normal thyroid gland. Sublingual location is less common than a lingual ectopia. True malignant transformation in ectopic thyroid tissue is extremely rare. Such a malignancy is virtually always diagnosed only after surgical excision of the lesion at pathological examination. This report discusses a case of ectopic thyroid follicular carcinoma in the right submandibular region in the absence of orthotopic thyroid, discovered by chance after the surgical excision performed for a preoperative ultrasonically and cytologically misdiagnosed submandibular gland adenocystic carcinoma. The possible aetiology of such an unusual anatomical relationship is discussed as well as the importance of thyroid scanning, ultrasound and/or CT in neck lumps. ( info)

12/892. neurothekeoma, a rare tumour of the tongue.

    Neurothekeomas are benign tumours mostly arising in the face and upper limbs predominantly in young women. Histologically they can be classified as cellular or myxoid, and complete surgical resection is the treatment of choice. In this case of a neurothekeoma located in the anterior tongue of a child, cryotherapy was used as the treatment modality, in order to avoid a greater loss of tongue function. ( info)

13/892. Fine needle aspiration cytology of primary non-Hodgkin's lymphoma of the tongue. A case report.

    BACKGROUND: Fine needle aspiration cytology (FNAC) of extranodal non-Hodgkin's lymphoma of the tongue has rarely been described. CASE: A 47-year-old male was referred to the cytology laboratory for FNAC of a 3-cm-diameter swelling on the dorsum of the tongue, with a primary clinical diagnosis of soft tissue tumor. FNAC smears showed discrete, monomorphic, round to oval cells with scanty, deep blue cytoplasm. The nuclear margin was regular, with occasional prominent nucleoli and fine nuclear chromatin. The background showed many lymphoglandular bodies. The cells were strongly positive for leukocyte common antigen. A cytologic diagnosis of high grade non-Hodgkin's (NHL) was offered and subsequently confirmed by histopathology. CONCLUSION: Primary NHL of the tongue is relatively rare. As there are no characteristic clinical features of extranodal NHL of the tongue, FNAC may be useful for rapid diagnosis and management of such cases. ( info)

14/892. US and CT findings of multicentric leiomyosarcomatosis.

    This article presents a case of leiomyosarcomatosis with widespread lesions involving the soft tissues and the most unlikely organs such as thyroid and salivary glands, pancreas, ligamentum teres, bladder wall, and bones without lymph node or distant metastasis. The CT and US findings of this rare phenomenon are discussed with regard to the literature. ( info)

15/892. lung and aero-digestive cancers in young marijuana smokers.

    Marijuana has been shown to be one of the commonly abused substances in the world, especially among teenagers and young adults. Although its addictive potential and psychomotor side-effects have been widely publicized, the issue of possible carcinogenicity is not as well perceived. Marijuana smoke contains many of the same organic and inorganic compounds that are carcinogens, co-carcinogens, or tumor promoters found in tobacco smoke. We have encountered several young marijuana users with no history of tobacco smoking or other significant risk factors who were diagnosed to have lung or other aero-digestive cancers in our practice. Although there are several experimental and epidemiological studies suggesting an association of marijuana use as a possible cause of cancers, this issue remains controversial. It is hoped that our case presentation can help to stimulate further awareness and research into this issue. ( info)

16/892. Vascular transformation of sinuses in bilateral cervical lymph nodes.

    BACKGROUND: Vascular transformation of sinuses (VTS) in lymph node has been infrequently reported. We present a case of incidental VTS in bilateral cervical nodes discovered at the time of operation for tongue cancer. methods: Standard histopathologic review was undertaken. RESULTS: In this case, a spectrum of varied vasoformative patterns involving lymph nodes in either a pan-nodal or localized fashion were identified. The hilum was occupied by smooth muscle proliferation and adipose tissue. Two nodes also displayed similar features of angiolipomatous hamartoma. No metastatic carcinoma was found in lymph nodes with VTS. CONCLUSIONS: This case suggests that lymphovenous congestion and distention represented the major cause through which VTS developed.

17/892. A large maxillofacial prosthesis for total mandibular defect: a case report.

    We successfully fabricated a large maxillofacial prosthesis for replacement of a total mandibular defect resulting from surgical failure to reconstruct the mandible. Although a number of reports have described procedures for fabricating midfacial prostheses, there is little information on prostheses to compensate for total loss of the mandible. A 54-year-old woman was referred to the dentistry and Oral Surgery Division of the National Cancer Center Hospital with total loss of the mandible and the surrounding facial soft tissue. The facial prosthesis we used to treat this patient is unique in that it is adequately retained without the use of extraoral implants and conventional adhesives. This prosthesis is retained by the bilateral auricles and the remaining upper front teeth. We present details of the design of this large silicone maxillofacial prosthesis, with which we successfully rehabilitated the patient. ( info)

18/892. Evaluation and management of benign, non-congenital tongue masses in children.

    Lingual tumors are rare, primarily benign, lesions in the pediatric population. Congenital lesions, such as hemangiomas, lymphatic malformations, dermoids, hamartomas and thyroglossal ducts cysts, are seen more commonly. Primary, non-congenital lingual neoplasms are less common in children. We present three patients with benign lingual neoplasms. Evaluation, management, pathology and follow-up are discussed. ( info)

19/892. Angiocentric T-cell lymphoma: an extensive lesion involving the posterior tongue, hypopharynx and supraglottis.

    Angiocentric T-cell lymphoma, which in the past has been grouped with a variety of granulomatous diseases, occur uncommonly as a destructive condition of the posterior nasal space and midface. We report on a patient with a chronic granular ulcerative lesion involving the posterior tongue, hypopharynx and supraglottis. ( info)

20/892. Dedifferentiation occurring in adenoid cystic carcinoma of the tongue.

    A 61-year-old man came to the University of Granada School of dentistry complaining of a mass involving his ventral tongue. Histopathologic examination of the excised specimen showed adenoid cystic carcinoma in which cribriform and tubular patterns were observed, juxtaposed with an undifferentiated carcinoma, large-cell type. No cervical lymph node metastasis was present, and the patient is alive and free of disease 5 years after treatment. To our knowledge, no similar cases have been reported thus far, though other salivary gland malignancies have been described in association with undifferentiated carcinoma, especially in the parotid gland. These neoplasms have been highly aggressive, and the adequacy of the primary surgical resection may be critical in determining the ultimate prognosis and survival. ( info)
