ABSTRACT
A trichilemmal cyst is a skin adnexal tumor that usually occurs on the scalps of elderly women. We report a trichilemmal cyst in the submandibular area of a 16-year-old male, masquerading as a second branchial cleft cyst. During surgery, the mass was found to have invaded the submandibular gland and needed to be excised totally in continuity with the submandibular gland. To our knowledge, this is the first reported case of a trichilemmal cyst involving the submandibular gland. Although rare, a trichilemmal cyst may be considered in the differential diagnosis of cystic lesions in the submandibular area. It should also be differentiated from other cystic malignant tumors for its tendency to invade the surrounding structure.

Verruca vulgaris in the nasal cavity is derived from the stratified squamous epithelium. It is commonly seen in the nasal vestibule and characterized by exophytic proliferation and extensive surface keratinization. Recently, we observed a case of verruca vulgaris occupying the right maxillary sinus coexisting with an inverted papilloma in the nasal cavity. Two separate masses in the nasal cavity and maxillary sinus were removed by endoscopic surgery. To our knowledge, this is the first reported case of verruca vulgaris involving the maxillary sinus coexisting with an inverted papilloma in the nasal cavity.

Vestibular paroxysmia, which is caused by neurovascular cross-compression of the eighth cranial nerve, is characterized by recurrent vertiginous spells and other audiologic symptoms such as tinnitus, aural fullness and hearing impairment. Magnetic resonance image may show the eighth cranial nerve compression by vessels in the posterior fossa such as the anterior-inferior cerebellar, posterior-inferior cerebellar, basilar, or vertebral arteries. Medical therapy including carbamazepine, phenytoin or gabapentin and microvascular decompression of the eighth cranial nerve can be contemplated. Here, we report of a 51 year-old man who presented with recurrent vertigo attacks and tinnitus. His symptoms were aggravated by positional change. Videonystagmography and auditory brainstem response showed abnormal results. Magnetic resonance image showed the eighth cranial nerve compression caused by the vascular loop. The offending vessel was revealed as vertebral artery. He was treated with carbamazepine and showed no recurrent symptoms. We report this rare case with a review of the relevant literatures.

Castleman's disease, or angiofollicular lymph node hyperplasia, is a rare disorder that involves the proliferation of lymphoid tissue. The disease entity is classified into three pathologic subtypes, namely, the hyaline vascular, plasma cell, and mixed types; however, clinically, they are classified as unicentric and multicentric types. The former is treated primarily by excision, whereas systemic therapies have been used to treat the latter form, because of its more aggressive pattern. We report a case of a 17-year-old woman who underwent an excisional biopsy of one of the multiple affected cervical lymph nodes. A subsequent histopathologic examination revealed hyaline vascular Castleman's disease. One month later, the disease spontaneously regressed and no recurrence was observed over a 12-month period following the excisional biopsy.

We report on a 45-year-old man with a confirmed diagnosis of acute myopericarditis associated with Mycoplasma pneumoniae. He visited our emergency department due to high fever (39degrees C) via a primary clinic. We made a diagnosis of myopericarditis based on symptoms, cardiac enzymes, electrocardiography, and transthoracic echocardiography. Serology (particle agglutination) testing for M. pneumoniae IgG antibody was also performed. The IgG antibody titer was 1:80 on the second day of admission, and increased to 1:2,560 by the 12th day of admission. Therefore, we confirmed the diagnosis of acute myopericarditis associated with M. pneumoniae and subsequently treated him with azithromycin. The symptoms and laboratory findings improved, and he recovered uneventfully.
