1/37. Fine needle aspiration cytology of an intraductal papilloma originating in a sublingual gland. A case report.BACKGROUND: Intraductal papilloma of the salivary gland is a very rare tumor; only eight cases have been reported to date. Only histopathology has been used to investigate this tumor to our knowledge. There has not been any reported case of this tumor in a sublingual gland. CASE: A 3-cm oral floor mass with a lanulalike lesion in a 72-year-old female was aspirated. The cytologic features included various cellular smears containing compact clusters of papillary, radial, palisading, trabecular, tubular and buddinglike projected patterns; monomorphic columnar cells with oval-to-spindle nuclei basally located; abundant, finely vacuolar cytoplasm; indistinct nucleoli; and no squamous differentiated cells. A sublingual glandectomy was performed. Cytology, histology, immunohistochemistry and electron microscopy were performed with standard methods. The intraductal papilloma seems to have arisen within an excretory duct and differentiated into acinar cells. CONCLUSION: The cytologic findings of intraductal papilloma are unique and may allow its specific diagnosis on fine needle aspiration.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/37. Sialadenoma papilliferum of the palate: case report and literature review.Sialadenoma papilliferum (SP) is a rare tumor of salivary gland ducts which bears a strong histologic resemblance to the more common syringocystadenoma papilliferum (SCAP). We report a case occurring on the palate of a 50-year-old man, and review the clinical and histologic features of this tumor. Because of the histologic similarities between these two tumors and squamous papillomas, polymerase chain reaction (PCR) for human papilloma virus (HPV) dna was performed on this tumor and on two cases of SCAP, with negative results. To our knowledge, this is the first case report of SP in the dermatopathology literature.- - - - - - - - - - ranking = 0.14285714285714keywords = gland (Clic here for more details about this article) |
3/37. Intraductal papilloma of the submandibular gland.Salivary tissue intraductal papillomas are rare, benign tumours that predominantly affect minor salivary glands. We report a case of an intraductal papilloma arising in the unusual site of the submandibular gland. The tumour was completely excised and recurrence is not expected. A brief review of this histologically distinct lesion is presented.- - - - - - - - - - ranking = 0.85714285714286keywords = gland (Clic here for more details about this article) |
4/37. A case of breast cancer associated with juvenile papillomatosis of the male breast.Juvenile papillomatosis of the breast (JPB) was first described in 1980 and is occasionally associated with breast cancer. The literature reports only four cases of JPB in males; none of them associated simultaneously with breast cancer. We present a case of a male with JPB associated with a ductal carcinoma in the same gland.- - - - - - - - - - ranking = 0.14285714285714keywords = gland (Clic here for more details about this article) |
5/37. Intestinal-type carcinoma of gallbladder. A histochemical and immunologic study.Two intestinal carcinomas of the gallbladder are presented. In both carcinomas the structure was papillary in superficial parts; the deeper ones also tended to an adenomatous structure. One of the tumors was bordered by a mucosa, with both intestinal- and antral-type metaplastic islands. The tumor was mainly a typical papilloma with malignant degeneration and infiltrative growth. The intestinal structure was morphologically clear in the papillary area of both carcinomas, but not distinct in the invasive part of the tumor. In both tumors, goblet cells and columnar cells with a distinct brush border were noted. Histochemical and immunologic methods were used in the identification of the glycoproteins of the tumor cells. With both methods the intestinal character of the tumor could be shown. A positive fluorescence was achieved with an intestinal antiserum in well-differentiated tumorous areas containing goblet cells, as well as in the intestinal metaplastic areas. In the same areas the gallbladder-specific antigen was negative. The antiserum isolated from the normal gastric mucosa and corresponding to neutral glycoprotein gave a positive fluorescence only in the nontumorous metaplastic gastric superficial-type epithelium and in the metaplastic antral-type glands.- - - - - - - - - - ranking = 0.14285714285714keywords = gland (Clic here for more details about this article) |
6/37. Intraductal papilloma in the parotid duct.Intraductal papilloma arising in the major salivary gland is uncommon. We treated intraductal papilloma of the parotid gland in a 41-year-old man with a 3-week history of a painless mass in his right parotid gland. Radiologic imaging studies revealed a well-circumscribed solitary mass, 1 cm in diameter, at the posterior edge of the right parotid superficial lobe. Complete excision of the mass was performed under general anesthesia. Pathologically, the mass consisted mainly of a cystically dilated salivary duct filled with dark brown muddy components and a cluster of growing papillary cells, leading to the diagnosis of intraductal papilloma. The literature on intraductal papillomas of the major salivary glands is reviewed, with particular focus on preoperative diagnosis of this condition.- - - - - - - - - - ranking = 0.57142857142857keywords = gland (Clic here for more details about this article) |
7/37. Intraduct papilloma of the palate. Report of a case.Salivary gland papillomas are rare tumours arising from ductal epithelium. Intraduct papillomas are the most rare of all duct papillomas. Only four intraduct papillomas have been described in a review of nearly 3100 epithelial salivary tumours. Intraduct papillomas are located almost exclusively in the excretory ducts of the minor salivary glands. However, also the major salivary glands may be affected. Microscopically, the tumour consists of fibrovascular papillae covered by a columnar or cuboidal epithelium. The authors describe an intraduct papilloma of the palate in a 74-year-old woman. The excision of the lesion was curative.- - - - - - - - - - ranking = 0.42857142857143keywords = gland (Clic here for more details about this article) |
8/37. Mullerian papilloma-like proliferation arising in cystic pelvic endosalpingiosis.This report describes an unusual epithelial proliferation occurring in pelvic cystic endosalpingiosis. A cyst mass lined by a layer of ciliated epithelial cells involved the posterior surface of the cervix and vagina. The epithelial proliferation within the wall resembled a mullerian papilloma with fibrous and fibrovascular cores lined by bland cuboidal epithelial cells. Other areas had a microglandular growth pattern resembling cervical microglandular hyperplasia, and focally there was a solid growth pattern. Foci of typical endosalpingiosis involved the surface of both ovaries and pelvic soft tissues. The cystic lesion recurred after partial cystectomy and drainage and was followed up radiologically and with periodic fine-needle aspiration. Part of the wall of the cyst removed 11 years after the original surgery showed an identical epithelial proliferation. MIB1 staining showed a proliferation index of less than 5%, contrasting with the higher proliferation index of a typical serous borderline tumor. The differential diagnosis is discussed. As far as we are aware, this is the first report of such a benign epithelial proliferation involving cystic endosalpingiosis.- - - - - - - - - - ranking = 0.28571428571429keywords = gland (Clic here for more details about this article) |
9/37. Hidradenoma papilliferum of nasal skin.Pathologic examination of an excisional biopsy specimen of a subepidermal nodule from the nasal tip of a 37-year-old black man demonstrated papillae covered by eosinophilic columnar epithelial cells, suggesting cylindric cell papilloma or well-differentiated papillary adenocarcinoma of nasal mucosa. The patient did not submit to further investigation of the sinonasal tract but sought attention 15 months later because of local recurrence of the lesion. A protuberant, 3-cm, cystic nodule of the subcutis over the left nasal ala and tip was excised completely and found to have characteristics of hidradenoma papilliferum, an apocrine gland neoplasm most commonly occurring in the anogenital skin of white women. This case demonstrates how easily an apocrine neoplasm arising near a mucocutaneous junction can be confused with a mucosal tumor, potentially leading to inappropriate treatment.- - - - - - - - - - ranking = 0.14285714285714keywords = gland (Clic here for more details about this article) |
10/37. Multiple inverted papilloma of the urinary bladder associated with glandular metaplasia of colic type. A case report.A case of inverted papilloma of the urinary bladder associated with glandular metaplasia is presented. A bladder urothelial carcinoma was suspected after clinic and endoscopic findings, but the diagnosis was established only on histological picture. Morphological and histochemical peculiarities of the lesions are described, considering the case being the first with such an association-according to our knowledge. The malignant potential of inverted papilloma and glandular metaplasia are discussed.- - - - - - - - - - ranking = 0.85714285714286keywords = gland (Clic here for more details about this article) |
