A child is reported with a scalp lipoma and underlying bony skull defect and porencephaly. The clinical picture is compatible with a diagnosis of encephalocraniocutaneous lipomatosis, although there is no alopecia overlying the lipoma and no scleral lesions. In addition, this child has unilateral ptosis and syndactyly. This report extends our appreciation of the phenotype of this neurocutaneous disorder.

Gastroduodenal intussusception is an extremely uncommon condition usually caused by the prolapse of a benign gastric tumor into the duodenum with subsequent invagination of a portion of the stomach wall. A rare case of this condition associated with a gastric lipoma is presented. Clinical manifestations may mimic many other disease entities and are nonspecific. Diagnosis, however, can often be made preoperatively with noninvasive tests, which are usually associated with more specific signs. Treatment involves reduction of the intussusception and surgical excision of the lead point, either endoscopically or through a formal laparotomy.

An 82-year-old woman had experienced progressive enlargement of a long-standing left upper lid mass for 3 weeks. The superior visual field was compromised secondary to mechanical ptosis from this lid lesion. Computed tomography showed a large lid mass with a low density signal, similar to intraorbital fat. The tumor was completely excised. Histopathologic examination showed an encapsulated tumor composed of mature adipose tissue interspersed with fibrovascular septa containing spindle-cells, confirming a diagnosis of spindle-cell lipoma.

Intracranial lipoma is a rare condition, and it is usually asymptomatic. We describe a 67 year old woman who developed blurred vision, diplopia, left sided oculomotor palsy, and ipsilateral ptosis during steroid treatment for giant cell arteritis. These symptoms were considered to be associated with aggressive giant cell arteritis, and the steroid dose was raised. Surprisingly, the symptoms increased, and further examination revealed an intracranial lipoma situated in the Meckel's cave. During tapering of the steroids her symptoms gradually improved. This is the first report demonstrating that steroids may induce hypertrophy of the fat tissue in the intracranial lipoma, causing compression of the cranial nerves passing through the cavernous sinus thereby mimicking the ocular symptoms sometimes associated with aggressive giant cell arteritis.

Prolapse of subconjunctival intraconal orbital fat is a rare cause of an intraorbital mass lesion. Over the past several years, we have seen a number of cases in which this prolapsed fat was confused pathologically with a neoplasm of adipocytic lineage, specifically pleomorphic lipoma and atypical lipomatous neoplasm (well-differentiated liposarcoma). We report the clinical, histopathologic, and immunohistochemical findings in 21 specimens from 17 patients, all of whom presented with prolapsed intraconal orbital fat. All specimens were routinely examined and processed for light microscopy. Immunohistochemistry for CD34, CD68, S100 protein, vimentin, alpha-smooth muscle actin, and Ki-67, and Giemsa, Masson trichrome, and alcian blue histochemical stains were performed. Clinical and follow-up information was extracted from a chart review. The mean age (+/-SD) of the patients was 65.6+/-11.9 years (range: 41 to 85 y); 2 were women and 15 were men. Subconjunctival prolapsed orbital fat was localized in the superotemporal quadrant or lateral canthus around the rectus muscle below the lacrimal gland. The lesions were unilateral in 10 and bilateral in 7 patients. No recurrence was clinically evident over a mean (+/-SD) follow-up time of 2.5+/-3.2 years (range: 1 mo to 13.5 y). Histopathologically, all specimens showed an admixture of mature fat, fibrous septae lacking hyperchromatic cells, adipocytes with intranuclear vacuoles (Lochkern cells), multinucleated giant cells with a wreathlike configuration of normochromatic nuclei (floret cells), and varying numbers of histiocytes, lymphocytes, plasma cells, and mast cells. "Control" sections of normal orbital fat showed occasional Lochkern cells but lacked floret cells. By immunohistochemistry, the floret cells expressed only CD34 and vimentin, whereas the Lochkern cells expressed CD34, S100 protein, and vimentin. We conclude that subconjunctival herniated orbital fat commonly contains multinucleated floretlike giant cells, fibrous septae, and Lochkern cells, features that may result in diagnostic confusion with pleomorphic lipoma and atypical lipomatous neoplasms. Importantly, specific diagnostic features, such as aggregates of bland spindled cells associated with wiry collagen, as seen in pleomorphic lipoma, and enlarged hyperchromatic cells within fibrous septae, as in atypical lipomatous neoplasms, are entirely absent in herniated orbital fat. Multinucleated floret cells present in prolapsed orbital fat likely represent a reactive phenomenon, as they are not present in normal orbital fat.

We report the case of a newborn presenting with a pediculated mass arising from the anal margin. Antenatal sonogram and magnetic resonance imaging were unable to diagnose the precise nature of the lesion. Sacrococcygeal teratoma, an enterogenous cyst, a polyp, a prolapse or other perineal tumors were all proposed as possible entities. At birth, no other anatomic anomaly than this homogenous 2 cm para-anal lesion was seen. Excision of the mass was performed under general anesthesia. The postoperative histological exam showed mature fat cells. Reviewing the literature, there have been few previously reported cases of congenital perineal lipoma. It is a rare, benign and easy-to-treat condition that can be evocated by morphological sonography or magnetic resonance imaging (MRI).

Submucosal lipomas are usually harmless neoplasms arising from submucosal adipocytes. They are found most commonly in the colon, but may develop in any part of the gastrointestinal tract. Most colonic lipomas are asymptomatic and need no treatment, whereas larger ones (>2 cm) may present with abdominal pain, changes in bowel habits, rectal bleeding, and intussusception or prolapse. The literature on the endoscopic resection of colonic lipomas is limited owing to the increased risk of colonic perforation. In this paper, we describe a novel technique for the treatment of colonic obstruction resulting from a giant lipoma by placing two large clips at the narrow base of the lipoma and performing multiple cuttings on the mucosa covering the fatty tissue by using a needle-knife to facilitate the fat's discharge into the colon's lumen. Our case showed that the endoclipping of semi- or pedunculated large colonic lipomas not amenable for endoloop ligation and associated with cuttings of the mucosa covering the fat is a promising new technique, which avoids the risk of perforation or bleeding of the snare cautery, especially in high-risk patients.

We report a case of lipoma in the antrum of the stomach which prolapsed into the duodenal bulb and caused a duodenal ulcer, which was speculated to have been induced by the friction of its tip against the duodenal mucosa. Although the duodenal ulcer healed after the administration of a proton pump inhibitor, the symptoms of epigastric discomfort continued, which was suggested to be due to the prolapse. Therefore, a laparoscopic operation was conducted. The incidence of lipoma of the stomach is rare, and cases of its prolapse into the duodenum are few. Furthermore, it is extremely rare for it to cause a duodenal ulcer. Because these features made this case clinically interesting, we report it here.

Lipoma is relatively common in the colon but is less often in the small intestine. Most lipomas are incidentally detected at endoscopy and are usually small and asymptomatic. However, some of them can present with obstruction and/or intussusceptions. Surgical resection is commonly recommended to remove such significant lipomas with a limited pedicle and larger than 2 cm in size, as endoscopic resection may result in unfavorable complications such as intestinal perforations. We report a case of 62-year-old man presenting with hematochezia. Colonoscopy showed a submucosal tumor, about 50 mm in size, in the terminal ileum. A clinical diagnosis of lipoma was established based on the findings of colonoscopy and abdominal computed tomography (CT). As the patient complained of hematochezia and mild iron deficiency anemia associated with repeated tumor prolapse, we decided to remove his lipoma. Consequently, the lesion was completely removed en bloc. Although abdominal CT immediately after removal of the lesion showed a small amount of free air, conservative treatment was successfully carried out for the perforation. Histologically, the removed lesion was a lipoma.
