1/197. Brunner's gland adenomas associated with high-output congestive heart failure.Brunner's gland adenoma in the third portion of the duodenum is rare and only two such cases have been reported previously. A 35-year old man presented with high-output congestive heart failure. Profound iron deficiency anemia was corrected by transfusion, allowing detection of a duodenal tumor, which proved pathologically to be a Brunner's gland adenoma.- - - - - - - - - - ranking = 1keywords = gland, adenoma (Clic here for more details about this article) |
2/197. Eccrine angiomatous hamartoma: report of seven cases.Eccrine angiomatous hamartoma is a rare cutaneous lesion. Histologically it is characterized by the proliferation of eccrine glands, vascular structures and occasionally other elements in the middle and deep dermis; we now report seven further cases of this condition, two with lipomatous involvement and also discuss its nosology.- - - - - - - - - - ranking = 0.11871397933568keywords = gland (Clic here for more details about this article) |
3/197. Multiple pulmonary leiomyomatous hamartoma with secondary ossification.A 31-year-old woman presented with multiple pulmonary leiomyomatous hamartoma (MPLH) with secondary ossification. She had a past history of parosteal osteosarcoma. The pulmonary lesions were composed of spindle-shaped cells arranged in interlacing fascicles, among which glands or duct-like spaces were scattered. As some lesions contained bony tissues, it was unclear whether or not the pulmonary lesions were metastases of parosteal osteosarcoma. However, the majority of spindle-shaped cells were positive for alpha-smooth muscle actin, including cells proliferating around the bony tissues. Clonality analysis using a target of human androgen receptor (HUMARA) gene disclosed that the pulmonary nodules were polyclonal. These findings do not indicate that the lesions were metastatic. We would like to emphasize that MPLH can show osseous metaplasia.- - - - - - - - - - ranking = 0.11871397933568keywords = gland (Clic here for more details about this article) |
4/197. The spectrum of epidermal nevi: a case of verrucous epidermal nevus contiguous with nevus sebaceus.During the normal development of skin, pluripotential cells give rise to keratinocytes, sebaceous glands, hair follicles, apocrine glands, and eccrine glands. In epidermal nevi, these components emerge in an abnormal mixture within a circumscribed site. Many authors have categorized epidermal nevi based on their predominant component; however, there is often notable overlap that occurs within a single area or within contiguous areas. We report a verrucous epidermal nevus contiguous to a nevus sebaceus of Jadassohn. The categories of epidermal nevi are somewhat artificial. Our case supports the view that epidermal nevi have a spectrum of manifestations, including verrucous epidermal nevi and nevus sebaceus of Jadassohn.- - - - - - - - - - ranking = 0.35614193800704keywords = gland (Clic here for more details about this article) |
5/197. Brunner's gland hamartomas: report of three cases.Brunner's gland hamartoma is a rare duodenal tumor, which grew larger than 2 cm in diameter in a very limited number of cases. Since the first description in a patient with fatal duodenal intussusception by Cruveilhier in 1835, approximately 143 cases have been reported in the English literature, and only 25 cases had tumor growth to more than 2 cm in diameter. To the best of our knowledge, only 4 cases have been reported in taiwan. We present three of Brunner's gland hamartomas. In one patient the tumor was located on the secondary portion of the duodenum, which presented with massive tumor bleeding and measured 3.0 cm in diameter. The other two were both located on the duodenal bulb, which presented with abdominal pain and measured 2.0 and 1.3 cm in diameter, respectively. One of the patients received endoscopic ultrasonography which showed specific findings. Two patients received laparotomy and tumor excision; the other one received endoscopic polypectomy. All 3 patients recovered well without any complications.- - - - - - - - - - ranking = 0.71228387601407keywords = gland (Clic here for more details about this article) |
6/197. Spiradenoma arising in a nevus sebaceus of Jadassohn: case report and literature review.nevus sebaceus (NS) of Jadassohn is usually a verrucous plaque on the scalp or face that arises secondary to disordered development of epithelial, pilar, sebaceous, and apocrine structures. The emergence of neoplasia is a late stage in the natural history of NS. Although most neoplastic proliferations are benign, several malignant tumors have arisen in this lesion. We describe the first case of a benign spiradenoma arising in an NS on the scalp in a 72-year-old Caucasian woman. Reexcision was recommended to prevent the development of a second neoplastic process and to avoid the rare occurrence of a malignant transformation of the existing neoplasia. The patient declined reexcision and remains under observation. The spectrum of tumors arising in NS are described and are categorized according to behavior. Syringocystadenoma papilliferum is the most commonly observed benign growth, whereas basal cell carcinoma is the most frequently seen malignant process. The signs of tumor development (benign or malignant) within an NS are reviewed, and treatment recommendations are provided. The clinical course of rare and unique aggressive neoplasms originating in NS is summarized.- - - - - - - - - - ranking = 0.28771612398593keywords = adenoma (Clic here for more details about this article) |
7/197. Polypoid hamartoma of Brunner's gland of the duodenum.BACKGROUND/AIMS: Brunner's gland adenoma is an extremely rare but important entity. Controversy exists over its etiology and pathogenesis, but the present view is that it is a duodenal hamartoma with a predominance of Brunner's gland elements. methods: A case of a 76-year-old woman with a reddish pedunculated polyp prolapsing between the bulb and the second part of the duodenum seen at endoscopy and removed surgically through a longitudinal duodenotomy is presented. RESULTS: The cut surface of the tumor had a grayish color, revealing multiple cystic spaces which on microscopic examination proved to be enlarged Brunner's glands. The hyperplastic glands formed lobules which were surrounded by bundles of fibromuscular and connective tissue. In the adjacent duodenum, large numbers of lobules of well-differentiated Brunner's glands with mucus-secreting epithelial cells were seen. CONCLUSION: The reported case supports the theory that Brunner's gland adenomas are duodenal hamartomas with a predominance of Brunner's gland elements and further shows that a continuity exists in Brunner's glands of the tumor and those of the adjacent duodenum. copyright copyright 1999 S.

8/197. Chondromatous hamartoma of the thyroid gland: report of a case.A case of congenital chondromatous hamartoma of the thyroid gland in a male infant is reported. It presented as a congenital goitre. The thyroid swelling started to increase in size and became hard. It was excised. Histopathological examination revealed the tumour to be a chondromatous hamartoma of the thyroid gland. Reports of this condition in the literature are few.- - - - - - - - - - ranking = 0.71228387601407keywords = gland (Clic here for more details about this article) |
9/197. Laryngeal hamartoma: surgical management.A newborn female infant with severe inspiratory stridor was found to have a laryngeal non-encapsulated hamartoma in the supraglottic area, medial to the hyoid bone and extending into the petiole of the epiglottis. Histologic examination revealed an extremely uncommon glandular hamartoma. Surgical management in the newborn period consisted of conservative endoscopic excision combined with open laryngofissure. The hamartoma was removed in the newborn period to avoid tracheostomy, because decanulation after tracheostomy in infants can be difficult.- - - - - - - - - - ranking = 0.11871397933568keywords = gland (Clic here for more details about this article) |
10/197. adenocarcinoma of the rectum with associated colorectal adenomatous polyps in tuberous sclerosis: a case report.The authors present the case of a 17-year-old girl with tuberous sclerosis (TS) who presented with symptoms of intussusception. Although endoscopically diagnosed with multiple colonic polyps, presumed to be hamartomas, and an invasive rectal adenocarcinoma, postoperative pathology findings confirmed the rectal cancer and showed multiple colonic adenomas. Multiple colonic adenomatous polyps in a young girl with tuberous sclerosis is extremely rare. Furthermore, we believe that this is the first report of an invasive adenocarcinoma of the large intestine occurring in a patient with TS.- - - - - - - - - - ranking = 0.28771612398593keywords = adenoma (Clic here for more details about this article) |
