RESUMEN
A 57-year-old man was referred to our department with a mass in the sphenoid sinus. Surgical removal of the tumor was performed. However, a testicular mass was found that showed rapid growth. He had undergone inguinal orchiectomy. Five days after the urological surgery, he noticed visual disturbances and bilateral visual loss. Ophthalmological examination revealed total blindness, and magnetic resonance imaging revealed sphenoid mass growth. The patient underwent emergent removal of the tumor, and a diagnosis of malignant lymphoma was made. A final diagnosis of mantle cell lymphoma (MCL) in the testis and sphenoid sinus was made. After receiving treatment with intravenous corticosteroids and chemotherapy for lymphoma, his left vision completely recovered. Although his right vision was lost, he returned to normal social activities. This is the first report in the literature on MCL developing in the sphenoid sinus presenting with bilateral blindness and ipsilateral recovery.
RESUMEN
This report aimed to introduce a very rare presentation of congenital aural fistula and its treatment. A 13-year-old girl presented with a mass on the right temporal region with protrusion of the helix. She noticed a mass a month previously, and the mass gradually swelled with pain. Pus discharged from the pit behind the helix. Mastoiditis was suspected; however, the tympanic membrane was normal. Magnetic resonance imaging revealed a cystic mass in the temporal region. The surgical removal of the mass was performed using a postauricular incision. The mass was cystic and had a stem connected to the pit. Insertion of a probe into the pit showed a connection to the mass. The mass was totally removed with the skin around the pit. Histologically, the cyst connected to the fistula and its lumen was covered with squamous cells. A diagnosis of a congenital aural fistula developed posterior to the helix was made. Considering its location, the fistula had been formed between the third and fourth hillocks of the embryonal helix. Aural fistula developed posteriorly is very rare, and it mimicked a temporal tumor or mastoiditis with a protruding auricle. Careful observation of the skin and consideration from developmental aspects are needed for an accurate diagnosis.

Basal cell adenocarcinoma is a low-grade malignancy of the salivary glands. Basal cell adenocarcinoma of the minor salivary gland is an extremely rare disease that originates from the maxillary sinus. The histopathological characteristics of basal cell adenocarcinomas are similar to those of basal cell adenomas. However, basal cell adenocarcinomas can be differentiated from basal cell adenomas based on their tendency to invade surrounding tissues. Surgical resection is the first-line treatment for basal cell adenocarcinomas. An 86-year-old man underwent operations for a maxillary sinus tumor twice in our department. The pathological results of the tumor at both times revealed basal cell adenoma. After 4 and 5 years since the last operation, the tumor recurred, and the patient was treated with partial maxillectomy using Weber-Ferguson incision. We observed invasions to the surrounding tissue, and based on immunohistochemical findings, the patient was diagnosed with basal cell adenocarcinoma. Herein, we present an extremely rare case of basal cell adenocarcinoma arising from the maxillary sinus, in detail.
RESUMEN
A case of nasopharyngeal tuberculosis with cervical lymph node tuberculosis is reported. The patient was a 20-year-old female immigrant from Vietnam and cook apprentice. Her chief complaint was left neck swelling with pain for three months. She was diagnosed with left neck lymphadenitis at a previous hospital, which suspected malignant lymphoma and referred her to our hospital. At the time of the first visit, she had left lymph swelling with tenderness and granuloma-like masses in the nasopharynx. PET-CT showed accumulations in both the swollen left neck lymph and nasopharynx. The diagnosis of this case would appear to be nasopharyngeal cancer with left and neck lymph node metastasis or nasopharyngeal tuberculosis with cervical lymph node tuberculosis in addition to malignant lymphoma. Based on some examinations (biopsy, bacteria culture, and imaging), it was diagnosed as nasopharyngeal tuberculosis with cervical lymph node tuberculosis. Therefore, she was treated with anti-tuberculosis agent in respiratory medicine.
RESUMEN
We experienced a case of huge chronic thyroiditis with malignant lymphoma that caused dyspnea with tracheal stenosis, dysphagia with esophagus stenosis and recurrent nerve paralysis. In this case, thyroidectomy was performed and, after the surgery, there was no sign of breathing or swallowing difficulties, and it was confirmed by the postoperative computed tomography that the tracheal stenosis had improved. We considered two possible explanations for the preoperative right recurrent nerve paralysis. In the first, the right recurrent nerve could have suffered from mechanical stimulation such as compression and traction to the recurrent nerve due to enlargement of the malignant lymphoma together with chronic thyroiditis. The second possible explanation was that malignant cells had invaded neurons. We could not distinguish between the two possibilities, since this right recurrent nerve was spared and could not be examined histopathologically.
