Merkel cell carcinoma (MCC) is a rare and highly aggressive neuroectodermal carcinoma arising from mechanoreceptor Merkel cells. Multiple MCCs are even rarer. We report a case of two independent MCCs simultaneously present in the cheek of a patient, which were effectively and esthetically treated using a cheek flap. Punch biopsy performed in a 60-year-old woman admitted with a chief complaint of two skin-colored hard nodules in her left cheek, accompanied by an itching sensation, was suggestive of MCC. Accordingly, we performed sentinel lymph node biopsy through the modified Blair incision under general anesthesia, in cooperation with the head and neck surgery department. The defect was covered with a cheek flap by slightly extending the existing incision following wide excision with a safety margin of 1 cm. This paper is significant in that it introduces an effective reconstruction technique that maintains function using a cheek flap for the management of this rare case. In addition, this paper is the first to classify multiple MCCs according to the time of onset. We believe that this paper presents an effective alternative reconstruction technique with sentinel node biopsy through the modified Blair incision.

This study was carried out to evaluate the irritant potential of A mouthwash in hamster cheek pouch. The test substances were applied twice daily to right pouches of hamsters for 14 consecutive days. Animals were administered with A mouthwash, Listerine, saline and control solution, respectively. In order to evaluate the irritant potential in mucosa of hamster cheek pouch, we observed clinical signs, mortality, body weight changes and gross and histopathological findings for 14 days. In all groups, there were neither dead animals nor significant changes of body weights. In addition, there were no differences between saline and A mouthwash treated group in gross and histopathological findings. Therefore, these results suggest that there was no irritant potential of A mouthwash in hamster cheek pouch.

The prevalence of cheek lymphoma, especially a mucosa-associated lymphoid tissue lymphoma (MALT), is very rare. Non-specific symptoms and image findings of cheek lymphoma may mimic benign entities and make it difficult to diagnose. In this case report, we present a case of MALT lymphoma of the cheek mimicking benign entities on computed tomography and magnetic resonance imaging.

Pleomorphic adenoma is the most common benign mixed salivary gland neoplasm that accounts for 65% of all benign salivary glands tumors. While the majority arises from the parotid, only a 10% arises from the minor salivary glands. Pleomorphic adenoma of minor salivary gland in the palate is a common entity. However, they occur in the lip, cheek, tongue oropharynx and nasal cavity etc., rarely. We experienced a case of a 80 years old female presented a 10 years history of a right cheek mass which was proved to the pleomorphic adenoma on the histopathologic examination. We resected the mass and obtained good postoperative results. We report this case with a review of literature.

A solitary fibrous tumor is a relatively uncommon neoplasm that usually occurs in the pleura but occurs extremely rarely in the oral cavity. Reported herein is a rare case of a solitary fibrous tumor in the buccal cheek mucosa. A 50-year-old man visited the authors' hospital due to a buccal cheek mass whose size had increased. Excisional biopsy was done under local anesthesia. After the excisional biopsy, the patient was diagnosed to have a solitary fibrous tumor. In immunohistochemistry, the patient's solitary fibrous tumor was characterized by the expression of CD34 and CD99 on the neoplastic cells, and negativity for Bcl-2 and S-100. No recurrence or complication occurred for a period of 5 years. The growth of a primary solitary fibrous tumor in the buccal cheek mucosa is extremely rare and has been rarely reported in the South Korean medical literature. A solitary fibrous tumor must be distinguished from other spindle cell tumors. Presented herein is a case of primary solitary fibrous tumor in the buccal cheek mucosa. The relevant literature is briefly reviewed.

Purpose: With an increase in the population of immunocompromised patients, the incidence of maxillary sinus aspergillus infection has also escalated. Maxillary sinus aspergillosis is generally extended to the sinus antrum, base or thin orbital wall and ethmoid air cell region. We experienced a case of maxillary sinus aspergillosis which was extended directly to the soft tissue of the cheek. Methods: A 46-year-old man with acute myelogenous leukemia was consulted for the defect of the anterior wall of the maxillary sinus, and cheek. Radiologic and histologic findings were consistent with invasive maxillary sinus aspergillosis. The otolaryngology department performed debridement via endoscopic sinus surgery first. Coverage of the resulting defect in the anterior wall of the maxillary sinus and its inner layer was undergone by the plastic and reconstructive surgery department, using a pedicled superficial temporal fascia flap and a split thickness skin graft. The remaining skin defect of the cheek was covered with a local skin flap. Results: The patient went through an uneventful recovery. There was no recurrence during 6 months of follow-up. Conclusion: Maxillary sinus aspergillosis usually involves the orbit or the gingiva but in some cases it may directly invade soft tissues of the cheek. Such an atypical infection extending into the cheek may lead to a large soft tissue defect requiring coverage. Thus, any undiagnosed soft tissue defect involving the cheek or maxillofacial area, especially in immunocompromised patients, should be evaluated for aspergillosis. We present this rare case, with a review of the related literature.

Background: The cheek rotation flap has sufficient blood flow and large flap size and it is also flexible and easy to manipulate. It has been used for reconstruction of defects on cheek, lower eyelid, or medial and lateral canthus. For the large defects on central nose, paramedian forehead flap has been used, but patients were reluctant despite the remaining same skin tone on damaged area because of remaining scars on forehead. However, the cheek flap is cosmetically superior as it uses the adjacent large flap. Thus, the study aims to demonstrate its versatility with clinical practices. Methods: This is retrospective case study on 38 patients who removed facial masses and reconstructed by the cheek rotation flap from 2008 to 2015. It consists of defects on cheek (16), lower eyelid (12), nose (3), medial canthus (3), lateral canthus (2), and preauricle (2). Buccal mucosa was used for the reconstruction of eyelid conjunctiva, and skin graft was processed for nasal mucosa reconstruction. Results: The average defect size was $6.4cm^2$, and the average flap size was $47.3cm^2$. Every flap recovered without complications such as abnormal slant, entropion or ectropion in lower eyelid, but revision surgery required in three cases of nasal side wall reconstruction due to the occurrence of dog ear on nasolabial sulcus. Conclusion: The cheek rotation flap can be applicable instead of paramedian forehead flap for the large nasal sidewall defect reconstruction as well as former medial and lateral canthal defect reconstruction.
