  • A mixed case of multiple sebaceous gland adenoma and perianal gland adenoma was found in a 11-year-old male Shih Tzu dog. Grossly, many masses less than 1 cm in diameter of back skin and single red-brown mass about 0.5 cm in diameter of inner ear were noted. In addition one of light-pink mass 5 cm in diameter was presented in the anus. All of the masses were well demarcated and dome-shaped or papillated nodules. Histologically, the mass from back and ear were composed with multiple irregular shaped or sized lobules of sebaceous glands. Masses were containing mostly mature sebaceous cells and multifocal cystic degeneration with acellular and bright eosinophilic materials. And the mass from peri-anal area was well-circumscribed and composed of broad, anastomosing trabeculae of well-differentiated hepatoid cells. There were very low mitotic figures in all masses. Based on these results, this case was diagnosed as the multiple sebaceous gland adenoma and perianal gland adenoma.

  • Sebaceous carcinoma is extremely rare in the parotid gland. Recently, we experienced a case of carcinoma with sebaceous differentiation arising from the parotid gland in patient who was diagnosed as parotid adenoma carcinoma and underwent total parotidectomy. A 73-year-old male visited our department for the evaluation of 3-month history of infra-auricular mass combined with pain. Radiologic finding showed lobulated enhancing and solid mass with calcification in the right parotid gland. Initially, total parotidectomy with supraomohyoid neck dissection was performed. Pathological findings showed capsulated whitish mass with hemorrhage and cystic degeneration. Immunohistochemically, CK7, CK5/6, p63 were positive and CEA was negative. The intra-operative frozen section diagnosis was mucoepidermoid carcinoma. The permanent diagnosis was changed to adenocarcinoma, NOS(not otherwise specified). Fourteen months later, the newly developed mass was noticed on the operation bed. The mass was clinically diagnosed as recurred adenocarcinoma. Revision parotidectomy was performed and pathological findings revealed that the tumor was newly developed sebaceous carcinoma. We report a case of carcinoma with sebaceous differentiation in parotid gland with a review of literature.

  • SZ95 cell is an immortalized human sebaceous gland cell line that shows the morphologic, phenotypic and functional characteristics of normal human sebocytes. Sebocytes may play crucial parts in the pathophysiologic processes and disorders of the pilosebaceous unit. The secretory activity of the sebaceous gland is remarkably species-specific and acne is an exclusively human disease. Thus, this SZ95 cells offer possibilities for investigations on the physiology of the sebaceous gland and its role in sebum-associated skin disease such as acne. In this study, we investigated the effects of 13-cis-retinoic acid (13-cis-RA) and spironolactone, frequently used as therapeutic agents of acne, on the lipid synthesis and proliferation of human sebocytes. Cell proliferation was determined by MTT assay and cytoplasmic lipid droplets was shown by Oil-red a staining. Total lipid levels were biochemically estimated by the sulfo-phospho-vanilline reagent. 13-cis-RA and spironolactone significantly inhibited proliferation and lipid levels in a dose-dependent manner. Combined treatment with testosterone and 13-cis-RA or spironolactone resulted in a lower total lipid levels than that with androgen alone. These observations indicate that 13-cis-RA and spironolactone are potent inhibitors of both cell proliferation and lipid synthesis in human sebocytes. We will provide experimental evidence that this human sebocyte cell line serves as an adequate tool for evaluating the anti-lipogenic activity of various compounds potentially useful for the bioactive cosmeceutical ingredients on acne skin, and studying the intracellular biochemical markers depending on the types of compounds from various sources.

  • Muir-Torre syndrome is defined by concurrent or sequential development of internal malignancy and sebaceous neoplasm or multiple keratoacanthomas. Muir-Torre syndrome is very rare, with only 205 cases reported in the literature. We reported a patient with Muir-Torre syndrome with three internal malignancies. A 64-year-old patient with a history of breast cancer, stomach cancer and colon cancer visited our department for treatment of the skin lesion that occurred five years before on the left cheek. The lesion was excised completely with a resection margin of 1 cm, followed by full-thickness skin graft from left postauricular area for reconstruction. Histopathology revealed a $0.2{\times}0.2{\times}0.1cm$ sized sebaceous carcinoma with 4 mm safety margin. The skin graft was well taken within 7 days after surgery and the patient was discharged to outpatient follow-up. There was no complication related with surgery. Muir-Torre syndrome is very rare, as are sebaceous gland tumors. So if a cancer of the sebaceous gland is diagnosed, screening workup for internal malignancy is recommended. Because of its good prognosis, surgical removal of primary or metastatic cancers may be curative and should be attempted where possible.

  • Efficiency study of chamomile and Thyme essential oil about the basal layer & sebaceous gland in dry-skin induced by surfactant is as following : 1. Formal observation of outer skin layer and basal layer There was refreshing effects about Surfactant induction skin inflammation in Chamomile, Thyme essential oil processing group but effect in surface layer appeared by higher thing in Chamomile essential oil and it could know that thing which do not use Thyme essential oil in case Thyme essential oil is ultraviolet rays allergy at skin care because Melanocyte appear on the surface is bigger than Chamomile essential oil that it was usefully reaction in basal layer. 2. Formal observation result of sebaceous glands. There are few damages in all group but there is recuperative through excessive water damage by excessive a sebaceous gland made of mulberry bark secretion because Thyme essential oil application group cause chapped skin phenomenon after surface-active agent processing but is seen that difference does not exist greatly and Thyme essential oil that general skin is strong in permeation is effective, but Surfactant induction skin inflammation estimates that Chamomile essential oil is effective. Therefore, it was considered that use of Chamomile essential oil is effectiveness than Thyme essential oil by essential oil used for recovery after damage of inflammation etc..

  • Sebaceous carcinoma is a relatively rare and aggressive malignant tumor. Periocular area (especially eyelid) is the most common lesion to occur, and the most common extraocular lesion is the parotid gland. Because the lesion also mimic other benign inflammatory diseases, this leads to delayed diagnosis or misdiagnosis. Here, we report a 58-year-old male patient who presented with a non-tender painless left parotid mass after wide excision of sebaceous carcinoma in the left eyelid two years ago. When he was diagnosed with sebaceous carcinoma of left eyelid, there was a small left parotid tumor on the computed tomography. But no further examination and treatment were performed. Two years later, physical examination revealed growing parotid tumor and multiple neck nodes on the left side. After radical parotidectomy and neck dissection, histological examination showed a sebaceous carcinoma and neck node metastasis. Considering the aggressiveness of sebaceous carcinoma, further evaluation for parotid glands should be considered when sebaceous carcinoma of the eyelid was discovered. Postoperative chemoradiotherapy was performed for disease control. Follow up after two years, and computed tomography showed no sign of recurrence.

  • Several physiological skin changes such as vernix caseosa, cutis marmorata, physiologic desquamation, and sebaceous hyperplasia have been described in the neonatal period. There are also clinical characteristics of skin peculiar to neonate and infancy. Skin disorders observed during neonatal and infancy period can be divided into transient skin lesions, birth marks, and other diseases. Transient skin lesions include milia, sebaceous gland hyperplasia, erythema neonatorum, transient neonatal pustular melanosis, and acne neonatorum. Nevocellular nevus, mongolian spot, vascular malformation, hemangioma, epidermal nevus, and sebaceous nevus belong to birth marks. There are several common skin diseases such as miliaria, diaper dermatitis, atopic dermatitis, seborrheic dermatitis, and cutaneous candidiasis.

  • The differentiation of the sebaceous gland is remarkably species-specific and sebocytes may play crucial parts in the pathophysiologic processes and disorders of pilosebaceous unit SZ95 cell is an immortalized human sebaceous gland cell line that shows characteristics of normal human sebocytes, In this study, we investigated the effect of testosterone and the anti-androgenic effect of 13-cis-retinoic acid (13-cis-RA) on lipid synthesis in SZ95 cells. Cytoplasmic lipid droplets were shown by Oil-red staining. The majority of the SZ95 cells positively labeled with Oil-red dye, while HaCaT cells negatively labeled with Oil red dye. Total lipid level of SZ96 cells is higher 4 times than that of HaCat cells. Testosterone markedly increased 2 times lipid synthesis of SZ95 cells in compared with control. 13-cis-RA significantly inhibited lipid synthesis and cell proliferation in SZ95 cells. Combined treatment with testosterone and 13-cis-RA resulted in a lower total lipid levels than that with androgen alone. In conclusion, SZ95 cells well resembled the morphologic and functional characteritics of normal human sebocytes. This in vitro model could provide a valuable tool for the study of sebocytes with a key role in pathophysiology and differentiation of sebaceous glands.

  • Sebaceous carcinoma (SC) is a rare tumor, accounting for approximately 0.7% of skin cancers. SC can be classified as ocular SC (OSC) or extraocular SC (EOSC) depending on its location. Because EOSC accompanied by metastases is rare, there is a paucity of data about EOSC accompanied by metastasis. This study presents a case of an aggressive EOSC of the scalp with lymph node metastases. The patient underwent wide local excision of the primary tumor with a 1 cm safety margin and bilateral radical lymph node dissection. However, recurrence was observed 1 month after surgery. Radiation therapy and resection were performed for the recurrent tumor. However, distant metastases to both lungs eventually occurred. Here, we describe a rare recurrent case of EOSC of the scalp with distant organ metastasis with a review of the literature.

  • The aqueous Green tea comes to be used with the Oriental medicine plant, it has the numerous health benefits, including antioxidant, anti-inflammatory, and anti- carcinogenic properties. Epidermal progenitor cells give rise to multiple skin lineages: hair follicle, sebaceous gland and the overlying interfollicular epidermis. Sebocytes are the cells of the sebaceous gland, which synthesize and accumulate lipid dropolets. In order to determine the effect of Green tea on lipid production, several experiments were performed in SZ95 cells (sebocytes). We found that Green tea increased lipid droplets compared with control in a dose-dependent manner. Human sebaceous glands produce sebum, a lipid mixture of squalene, wax esters, triglycerides, cholesterol esters, and free fatty acids that is secreted onto the skin. Therefore, to investigate the effects of Green tea on intracellular lipid levels, we treated SZ95 cells with Green tea, and then examined cholesterol and triglyceride levels. After treatment of the cells with Green tea, the cholesterol and triglyceride levels of SZ95 cells were increased significantly in a dose-dependent manner.
