  • Basal cell tumors from 53 dogs were examined histologically and classified as basal cell adenoma(n=44), granular basal cell adenoma(n=1), basal cell carcinoma(n=3), basosquamous cell adenoma(n=1), basosquamous carcinoma(n=4) on the basis of malignancy and squamous metaplasia. Female was twenty three and male was thirty. Affected dogs are usually 5.6 years and sex predilection have not been seen. None of tumor examined was metastasized into other organs. Distinct patterns identified in the basal cell adenoma are solid(n=15), cystic(n=13), adenoid(n=8), medusa(n=5) and ribbon(n=3). Solid basal cell adenoma is common type in benign basal cell adenoma. Only one neoplasm was granular basal cell adenoma which was characterized by eccentric nucleus and abundant granular cytoplasm. Basal cell carcinoma showed anaplastic appearance histologically and had atypical basaloid epithelial cells and multinucleated giant cells with moderate number of mitotic figures. Both basosquamous cell adenoma and carcinoma had squamous metaplasia.

  • Purpose: Basal cell adenoma of the salivary gland is an uncommon type of monomorphic adenoma. The most frequent location is parotid gland. It usually appears as a firm, mobile and slow-growing mass. Originally the term "basal cell adenoma" is described as a benign salivary gland tumor comprised of uniform appearing basaloid cells which are arranged in solid, trabecular, tubular, and membranous patterns. But the myxoid and chondroid mesenchymal like component as seen in pleomorphic adenoma is lacking in basal cell adenoma. We report a case of basal cell adenoma of parotid gland with review of the literatures. Methods: The 59-year-old female patient was referred to our department with a painless palpable mass in the left preauricular region for about 1 year. Movable and nontender subcutaneous mass was palpable. There was no evidence of cervical metastasis in computed tomography and ultrasonography. On fine needle aspiration cytology, pleomorphic adenoma was suspected. Under general anesthesia, superficial parotidectomy including tumor was performed. The biopsy result was basal cell adenoma. Results: Long-term follow-up for 54 months showed favorable result without evidence of recurrence except for temporary facial nerve weakness right after the surgery. Conclusion: Basal cell adenoma is the third most frequent benign tumor of the salivary gland, following pleomorphic adenoma and Warthin's tumor, although the incidence is low. The typical clinical feature of the basal cell adenoma is slowly growing, asymptomatic, and freely movable parotid mass. Basal cell adenoma should be also considered as a differential diagnosis of the parotid gland benign tumor.

  • The concurrence of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) in a single tumor is rarely encountered. We report a case of BCC and SCC in a single tumor in the anterior auricular area. A 70-year-old woman had been diagnosed with BCC by a punch biopsy performed at a dermatology clinic. We performed wide excision of the tumor with an ulcer in the anterior auricular area. Analysis of the biopsy specimen revealed the presence of both BCC and SCC in the tumor. This case illustrates that it is necessary to establish a precise diagnosis and formulate appropriate surgical and treatment plans considering the possibility that two carcinomas may coexist, although the possibility is low in patients with skin cancer.

  • Basal cell adenocarcinoma is an epithelial neoplasm which is cytologically and histomorphologically similar to basal cell adenoma but is different because of the infilitrative growth. This tumor, a rare salivary gland tumor newly classified as basal cell adenocarcinoma by the WHO in 1991, is infiltrative, locally destructive and tends to recur but metastasis is less common. The differential diagnosis includes basal cell adenoma, adenoid cystic carcinoma, and basaloid squamous carcinoma. Nearly 90 percent of these tumors occurr in the parotid gland and can be classified into low grade carcinomas with a relative good prognosis. Basal cell adenocarcinoma of minor salivary gland is very rare and has a less favorable clinical course compared with that of the major salivary glands. This is a case of basal cell adenocarcinoma occurring at the minor salivary gland of the soft palate. We treated this patient with block excision and adjunctive radiation therapy.

  • Nevoid basal cell carcinoma syndrome(NBCCS) is a autosomal dominant disorder, and its major manifestations are multiple basal cell carcinoma, keratocystic odontogenic tumor, rib anomalies, palmer and plantar pits, calcification of the falx cerebri. Keratocystic odontogenic tumor(KCOT) is defined as intraosseous tumor of odontogenic origin with a characteristic lining of parakeratinized stratified squamous epithelium and potential aggressive behavior. We report a case of a 3-year-old patient with nevoid basal cell carcinoma syndrome who initially presented with unilocular keratocystic odontogenic tumor in maxillary canine region. Keratocystic odontogenic tumor was treated by enucleation, and periodic follow-up check will be required for early diagnosis of additional diseases related with this syndrome.

  • A 10 year-old castrated male Maltese dog with a mass on the right carpal joint was referred to the Chungnam National University Veterinary Medical Teaching Hospital. Mass size was 0.5 cm in width, 0.8 cm in length and 0.8 cm in height. Surface of the mass was hairless and ulcerated, and also the peripheral furs of mass were discolored by continuous licking. This case was diagnosed as basal cell tumor by fine needle aspiration and histopathologic examination. This dog didn't lick the carpal joint after surgery.

  • Glioblastoma is the most aggressive common brain tumor in adults. Curcumin, from Curcuma longa, is an effective antitumor agent. Although the same proteins control both autophagy and cell death, the molecular connections between them are complicated and autophagy may promote or inhibit cell death. We investigated whether curcumin affects autophagy, which regulates curcumin-mediated tumor cell death in A172 human glioblastoma cells. When A172 cells were incubated with $10{\mu}M$ curcumin, autophagy increased in a time-dependent manner. Curcumin-induced cell death was reduced by co-incubation with the autophagy inhibitors 3-methyladenine (3-MA), hydroxychloroquine (HCQ), and LY294002. Curcumin-induced cell death was also inhibited by co-incubation with rapamycin, an autophagy inducer. When cells were incubated under serum-deprived medium, LC3-II amount was increased but the basal level of cell viability was reduced, leading to the inhibition of curcumin-induced cell death. Cell death was decreased by inhibiting curcumin-induced autophagy using small interference RNA (siRNA) of Atg5 or Beclin1. Therefore, curcumin-mediated tumor cell death is promoted by curcumin-induced autophagy, but not by an increase in the basal level of autophagy in rapamycin-treated or serum-deprived conditions. This suggests that the antitumor effects of curcumin are influenced differently by curcumin-induced autophagy and the prerequisite basal level of autophagy in cancer cells.

  • Most of salivary tumors are benign in nature and are typically diagnosed and classified based on their histopathological presentation. Basal cell adenoma of the salivary glands is a rare, benign disease accounting for 1% to 3% of salivary gland tumors. Despite its low incidence, basal cell adenoma is the third most common benign tumor of the salivary gland after pleomorphic adenoma and Warthin's tumor. It usually appears as a firm and slow-growing mass. Due to the prognosis, differential diagnosis with basal cell adenocarcinoma, adenoid cystic carcinoma and basaloid squamous cell carcinoma is required. In this report, we present two cases; a 62-year-old woman who presented with an asymptomatic, and slow-growing mass and a 64-year-old woman with a static-sized mass in the parotid gland. In both cases, the mass was completely excised, postoperative pathology reports confirmed the diagnosis of basal cell adenoma. We also review the literature and discuss this rare entity.

  • The basal cell adenoma of the parotid gland is rare benign disease, first described and adequately documented as a distinctive tumor from benigh mixed tumors(pleomorphic adenoma) by Kleinsasser and Klein in 1967. This tumors is an isomorphic epithelial tumor of salivery gland, characteristic of absence of myoepithelial cells which are present in pleomorphic adenoma and other salivery gland tumors. Clinicopathologically the tumors is very difficult to differentiate with pleomorphic adenoma or adenoid cystic carcinoma. The prognosis is excellent by complete extirpation of the tumor. The present report presents two cases of basal cell adenoma of the parotid gland seen in 63 year old man and 71 year old man in one-year period at Department of Surgery, Yonsei University, College of Medicine.

  • Basal cell adenoma (BCA) is a rare, benign neoplasm that most frequently arises in the parotid gland. We treated a 54-year-old female patient with BCA that had developed in the deep portion of the left parotid gland. The patient presented with gradual facial swelling with no other symptoms. We performed a total parotidectomy to excise the mass, but we preserved the facial nerve. Histopathology revealed a well-encapsulated mass. The tumor was composed of islands of comparatively uniform, small, dark, basaloid epithelial cells in the stroma. Histologic and immunohistochemical studies concluded that the BCA tumors were mostly trabecular. Postoperatively, there was no facial nerve weakness, and the tumor did not recur during the 24-month follow-up period.
