1/270. Retrorectal cystic harmatoma (tailgut cyst) in an infant: case report.We report the case of a day old infant who presented with a large cystic swelling in the sacroccoygeal area distorting the gluteal folds and displacing the anus anteriorly. Rectal examination revealed less than twenty five per cent of the lesion in retrorectal space, plain x-rays did not show any calcification. The infant had excision surgery at seven days of age and did well thereafter. Although most TGC cases were reported in adults the present case fulfills the anatomical and histological criteria for diagnosis, and it may be the first such case in a child less than one month old.- - - - - - - - - - ranking = 1keywords = area (Clic here for more details about this article) |
2/270. A case of juxtaglomerular cell tumor diagnosed preoperatively.A case of juxtaglomerular cell tumor, the fourth case in the world diagnosed preoperatively, was reported. Neither strict sodium restriction nor loading of upright position increased a grade of hyperreninemia observed at recumbant position on ordinary diet, but Pald elevated in response to them. Abnormal glucose tolerance was considered to be due to hypopotassemia. Selective renal arteriography revealed a small number of tumor vessels, a lucent area on the nephrogram and early appearance of the renal vein of the diseased side. Histologically, the tumor contained some canalicular structures among the polygonal nonepithelial tumor cells with rhomboid bodies. These findings suggested that this tumor was a hamartoma originated from the juxtaglomerular apparatus.- - - - - - - - - - ranking = 1keywords = area (Clic here for more details about this article) |
3/270. Spontaneous rupture of splenic hamartoma: a case report.Splenic hamartomas are rare. The authors report a case of spontaneously ruptured splenic hamartoma in a 5-month-old boy. This rupture led to the death of the child. If abdominal pain is present and a mass is palpated, the splenic hamartoma should be managed surgically in an expeditious manner. There have been only two known previous reports of spontaneous rupture of splenic hamartoma in adults, but none in children.- - - - - - - - - - ranking = 0.24530085663511keywords = pain (Clic here for more details about this article) |
4/270. Ictal bradycardia in a patient with a hypothalamic hamartoma: a stereo-EEG study.Little is known about bradycardia and cardiac asystole which occur during partial epileptic seizures, especially whether they relate to ictal involvement of well-defined cortical areas. Several reports based on simultaneous electrocardiographic and intracranial depth electroencephalographic monitoring have shown that either the fronto-orbital cortex or the amygdalohippocampal complex could be responsible for such cardiac variations. We performed stereo-EEG recordings in a patient with refractory localization-related epilepsy associated with a hypothalamic hamartoma. We found that other cortical areas, such as the frontocentral region and the temporal neocortex, can contribute to the genesis of ictal bradyarrhythmia. Second, the lesion per se, although located within the hypothalamus, is not involved with this phenomenon.- - - - - - - - - - ranking = 2keywords = area (Clic here for more details about this article) |
5/270. hamartoma of the urinary bladder.BACKGROUND: Hamartomas of the urinary bladder are extremely rare. We report on a case in a 58-year-old female who presented with the chief complaint of pain on urination. methods/RESULTS: cystoscopy revealed a solid tumor on the left posterior wall of the bladder. Transurethral resection of the tumor failed to provide a definitive pathological diagnosis of the tumor. Thus, we performed partial cystectomy. The pathological diagnosis was hamartoma arising from the urinary bladder. CONCLUSION: This is the ninth case diagnosed as urinary bladder hamartoma to be reported in the literature.- - - - - - - - - - ranking = 0.24530085663511keywords = pain (Clic here for more details about this article) |
6/270. A functioning eccrine hamartoma associated with Down's syndrome (46, xx,-21, t(21q21q).Pure eccrine hamartomas are very rare, and commonly present as localized areas of hyperhidrosis in normal looking skin. We describe a case of bilateral functioning eccrine hamartomas with macroscopically abnormal features in association with Down's syndrome.- - - - - - - - - - ranking = 1keywords = area (Clic here for more details about this article) |
7/270. Chondroid hamartoma presenting as a neonatal nasal mass.We present a case of a 3-month-old female with a right nasal mass. Upon evaluation with computed tomography, magnetic resonance imaging and angiography, a large right intranasal mass extending through the cribiform plate, displacing the dura, was noted. The patient underwent a combined midfacial degloving and bifrontal craniotomy for complete resection of the tumor mass. Pathologic evaluation demonstrated a mesenchymal tumor with spindle and stellate cells from which islands of immature cartilage emerged. The spectrum of histologic features closely resembled a mesenchymal chondroid hamartoma typically located in the chest wall. It is the first reported case of a chondroid hamartoma of the head and neck in the literature to date. We examine the characteristics and treatment of this unusual tumor.- - - - - - - - - - ranking = 7.8919081107928keywords = chest (Clic here for more details about this article) |
8/270. Polymorphic light eruption occurring solely on an area of naevoid telangiectasia.We report the case of a 60-year-old woman presenting with polymorphic light eruption occurring solely on an area of acquired naevoid telangiectasia. We have hypothesized that increased blood flow in the telangiectatic skin may reduce the threshold for expression of photosensitivity by permitting enhanced inflammatory cell trafficking to the overlying tissue.- - - - - - - - - - ranking = 5keywords = area (Clic here for more details about this article) |
9/270. 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 = 2keywords = area (Clic here for more details about this article) |
10/270. Eccrine angiomatous hamartoma: report of a case and literature review.Eccrine angiomatous hamartoma is a rare condition characterized histologically by increased numbers of eccrine structures and numerous capillary channels. patients characteristically have a solitary, congenital nodule that may be painful and that may show hyperhidrosis. It is important to recognize this condition because it is a benign lesion for which aggressive treatment is not indicated. We report the case of a congenital eccrine angiomatous hamartoma that had a firm nodule studded with blue papules.- - - - - - - - - - ranking = 0.24530085663511keywords = pain (Clic here for more details about this article) |
