We report an extremely rare case of primary squamous cell carcinoma of the stomach. A 69-year-old man was admitted to our hospital with a 2-month history of dysphagia and tarry stools. Endoscopic examination revealed a cauliflower-shaped protruding mass along the lesser curvature of the gastric cardia. Biopsy of the lesion revealed squamous cell carcinoma of the stomach. Computed tomography revealed a thickened stomach wall and a mass protruding into the gastric lumen. Total gastrectomy with splenectomy, distal pancreatectomy, and Roux-en-Y reconstruction was performed, together with a lower thoracic esophagectomy via a left thoracotomy. Histopathological examination of the specimen revealed well-differentiated squamous cell carcinoma of the stomach. Postoperative follow-up was uneventful for the first 18 months. However, multiple liver metastases and para-aortic lymph node metastasis developed subsequently. Despite systemic combination chemotherapy, the patient died because of progression of the recurrent tumors. Here, we review the characteristics of 56 cases of gastric squamous cell carcinoma reported in Japan.

The patient was a 77-year-old man with chief complaints of left lower jaw pain and discomfort. He had pain centering on the left lower jaw and was diagnosed with trigeminal neuralgia involving the third branch of the trigeminal nerve by a local physician. The pain subsided temporarily by administering carbamazepine, but recurred in the same region. He was subsequently referred to our ambulatory pain clinic. Sudden bouts of pain occurring dozens of times a day were noted, with depression, anorexia, lack of motivation, dry mouth, cold extremities, and dry skin. A crimson colored and slightly enlarged tongue with teeth marks on the border, crimson color on the tip, and white moss, were noted in the tongue examination. Pulse examination revealed a sunken pulse and abdominal examination noted epigastric discomfort and weakness (2/5) of the lower abdominal region. Mandibular nerve block temporarily resolved the pain, but there were repeated cycles of exacerbations, between which the feeling of discomfort persisted. Yokukansan extract (7.5 g divided into 3 doses per day) was administered, 35 months after the first clinic visit to address the discomfort that persisted after resolution of pain. Discomfort resolved. Currently, the patient still does not require mandibular nerve block or analgesics. Here we report this case in which Yokukansan was effective against discomfort in trigeminal neuralgia.
