Benign symmetric lipomatosis was initially described in 1846 by Sir Benjamin Brodie. In 1888, Otto Madelung presented 33 cases of benign symmetric lipomatosis and described the classic“horse collar”cervical distribution of the lipomatous tissue. Launois and Bensaude described benign symmetric lipomatosis as a distint syndrome characterized by a diffuse, symmetric, fatty accumulation in the cervical region. This disease is rare condition affecting mostly middle aged alcoholic men and associated with many systemic diseases such as diabetes mellitus, hyperuricemia, renal tubular acidosis, liver enzyme abnormality etc. The condition does not spontaneously involute and surgical excision is the only proven method of treatment, and recurrence is frequent. We experienced six patients of benign symmetric lipomatosis who underwent surgical excision via collar incision which afford wide exposure of the entire cervical area. We report them with the review of literature.

Lipomas are the most common benign mesenchymal tumors composed of mature adipocytes. They are usually slow-growing, soft and asymptomatic masses. Angiolipomas are rare benign soft tissue tumors that are distinguished from common lipomas by a marked degree of vascularization. The diagnosis and prognosis of angiolipomas are based entirely on the findings of histological evaluations. Angiolipoma, showing characteristics of both lipoma and hemangioma, usually develop in the trunk and extremities, and rarely arise in the head and neck region. Angiolipoma of the cheek is very rare. This report presents the clinical and histopathological features of infiltrating angiolipoma excised from the cheek.

Head and neck cutaneous metastasis of advanced gastric cancer is uncommon, and scalp metastasis is particularly rare. We present the case of a 60-year-old man who was diagnosed with cutaneous metastasis on the scalp originating from advanced gastric cancer. The patient was referred to the plastic surgery department for a scalp mass near the hairline. He had been diagnosed with advanced gastric cancer and undergone total gastrectomy and Roux esophagojejunostomy 3 years previously. The differential diagnosis for a single flesh-colored nodule on the scalp included benign tumors such as epidermal cyst or lipoma; therefore, the patient underwent excision and biopsy. In the operative field, the mass was found to be located in the frontalis muscle. The biopsy result showed that the mass was a metastatic lesion of advanced gastric cancer. Whole-body computed tomography revealed a gastric tumor with blood vessel infiltration, peritoneal carcinomatosis, liver metastasis, and multiple disseminated subcutaneous metastases. Although scalp metastasis originating from an internal organ is extremely rare, plastic surgeons should always consider a metastatic lesion in the differential diagnosis if a patient with a scalp lesion has a history of malignant cancer.

Fibrolipomas are a rare microscopic variant of lipomas, characterized by mature adipose tissue interspersed with dense fibrous connective tissue. These lesions are rarely observed in the head and neck region and represent <0.6% of all benign tumors of the larynx and hypopharynx. Their clinical presentation depends on the location and size of lesions. Patients present with variable symptoms; however, fibrolipomas of the larynx and hypopharynx are clinically important because these tumors can cause unpredictable airway obstruction, particularly during general anesthesia induction. We present a case of a hypopharyngeal fibrolipoma in a 61-year-old patient with frequent dyspnea, dysphagia, and muffled voice. Laryngoscopy revealed a well-demarcated pedunculated ovoid mass involving the larynx. We performed laryngomicrosurgery using a carbon dioxide laser for surgical excision and subsequent evaluation confirmed the diagnosis of fibrolipoma. We report a case of hypopharyngeal fibrolipoma, together with a literature review.

Madelung's disease (MD) is a rare disease characterized by diffuse, nonencapsulated, multiple fat masses in different areas of the body. In this case report, we present a case of MD in Asia and its management. A 66-year-old man with a history of hypertension presented with massive growth of soft tissue around the neck, breasts, upper back, and lower abdomen. Preoperative magnetic resonance imaging revealed remarkably hypertrophic fat tissue around the neck and anterior chest was wall, which consistent with the diagnosis of MD. Multiple linear incisions were made on the neck and 763, 186, 635 g of posterior, right, and left fat tissues were excised, respectively. A single wide, transverse incision was done to excise 1,072 g of fat from the upper back. Masses of both breasts were excised, preserving the inferior pedicle, weighing 1,086 (right) and 1,164 g (left). The recovery was optimal and the patient was discharged without complications. In this case, we excised the adipose masses as much as possible and improved contour and symmetry. However, the fat infiltrations in the patient were diffusely distributed, making total fat excision difficult. This rare case report may help in managing patients with MD.

Lipoblastoma is a rare benign tumor that usually originates in children from the embryonic lipid cells of the extremities. This condition shows an early childhood occurrence, a benign nature without metastasis, a cellular composition of mainly mature lipid cells and an ability to differentiate into a simple lipoma. We have experienced a 15 month old girl who had developed a lipoblastoma in the right anterior mediastinum. Surgical resection was carried out without complications. Her postoperative course was uneventful. She has been well 6 months after the operation.

The plunging ranula or cervical ranula is amucous extravasation cyst of the sublingual gland. It is slightly common in females, shows no side preference, and is more prevalent in the second and third decades of life. It typically manifests as a painless, nonmobile swelling in the neck. The pathogenesis of plunging ranula is the discontinuities of the mylohyoid muscle in a position that would allow extravasation of sublingual gland mucin. The histologic appearance is characteristically of a cyst, devoid of epithelium or endothelium, with a vascular fibro-connective tissue wall containing some chronic inflammatory cells and macrophages stuffed with mucin. The correct diagnosis is essential for the most effective treatment, which is exicision of the sublingual gland. The plunging ranula must be differentiated clinically and histomorphologically from thyroglossal duct cyst, dermoid cyst, branchogenic cyst, lymphangioma, laryngocele, lipoma, hemangioma, cervial thymic cyst, cysts of the parathyroid or thyroid gland, lymphadenopathy, abscess, or tumor. We report a case and review the literatures, in our case, 23-year old man were diagnosis as plunging ranula after have been taken sialogam, MRI, etc. He underwent surgery via a cervical approach. The ranula reached the anterior neck by passing through a dehiscence in the mylohyoid muscle. A pseudocyst was extirpated. Although total sublingual gland excision was not performed, no recurrence was observed during 6 months follow-up periods.

Purpose: The authors intended to analyze the operative results of tarsal tunnel syndrome. Materials and Methods: Twenty-one patients with tarsal tunnel syndrome were followed for more than 1 year after operation. The mean age was 44 years, and the mean follow up period was 2 years and 9 months. Clinically preoperative and postoperative AOFAS ankle-hindfoot score and visual analogue scale for pain were analyzed. Radiologically the cause of disease was investigated, and the size of mass was measured, if possible. The duration of symptom, the presence of space occupying lesion (SOL), the effect of epineurolysis were statistically analyzed to see the relation with the operative results. Results: Operative release of tarsal tunnel was done in all cases, and epineurolysis was done in 11 cases. The causes of the disease were 10 soft tissue masses, 7 talocalcaneal coalitions, 1 nonunion of medial talar process fracture, and 1 pes planovalgus, and 3 idiopathic cases. The masses were subdivided into 7 ganglions, 2 neurilemmomas, and 1 lipoma. There was 1 case of combined talocalcaneal coalition and ganglion. Clinically AOFAS ankle-hindfoot score was increased from 62.7 points preoperatively to 84.3 points postoperatively. Visual analogue scale was improved from 6.5 preoperatively to 2.2 postoperatively. Two cases were graded as unsatisfactory. One was severe pes planovalgus, and the other was idiopathic case. The duration of symptom and the epineurolysis were not related with the results. However the presence of space occupying lesion was significantly related with the good results. Conclusion: Early operative release of tarsal tunnel appears to be important for the improvement of symptom. However the prognosis is limited in case that there is no SOL.

This study examined the relative incidence of feline cutaneous tumors according to age, breed, sex, and site predilection for these tumors. Biopsy samples were examined and diagnosed from the histopathology. Over a 72-month period, from January 2013 to December 2018, 478 feline biopsy samples were received from veterinary practitioners across the nation. Of these, 232 (48.54%) cases were skin masses. Among them, 73.71% (171/232) were neoplastic lesions and 26.29% (61/232) were non-neoplastic. Twenty-two different types of cutaneous neoplasms were diagnosed as epithelial tumors (15.79%), mesenchymal tumors (83.63%), or melanocytic tumor (0.58%). The four most common tumors were mast cell tumor (60.23%), lipoma (5.85%), basal cell carcinoma (4.68%), and fibrosarcoma (4.68%), which comprised 75.44% of all tumor cases. Cutaneous tumors were located most commonly in the head of the cat (43.27%) and in the Korean shorthaired breed (75.44%). According to this study, cutaneous tumors were the most common tumor types in feline neoplasms in Korea. The incidence of cutaneous tumors was highest in Korean shorthaired cats, the most prevalent breed in Korea. Mast cell tumors are the most common skin neoplasm in Korea and can affect very young cats.

Neurilemmoma is a benign encapsulated nerve sheath tumor originated from peripheral nerve. Previously its preoperative diagnosis had mainly depended on the history, physical examination, electrodiagnostic test, ultrasonography, bone scan. But only with these diagnostic modalities, exact preoperative diagnosis was nearly impossible. Therefore operation was performed under the impression of lipoma or just simple soft tissue tumor. Recently, the advent of magnetic resonance imaging(MRI) has made it easier to diagnose neurilemoma before surgery. MRI also helps to determine the extent of lesion and operative procedures. We performed marginal excision in 24 cases, evaluated those cases with respect to the sex, age, location, chief complaint, duration of illness, preoperative diagnosis, involved nerve, imaging studies, size of mass, complication, duration of follow-up and report with review of the literature.
