ABSTRACT
OBJECTIVES: Vascular leiomyoma (angioleiomyoma) of the nasal cavity is an extremely rare tumour. Following a thorough review of relevant literature, we found that such tumours are more common in females. Only 4 of 30 reported cases have been found in male patients. Moreover, considering the site of the lesion within the nasal cavity, only 3 of these 30 cases originated from the nasal vestibule. Hereby, we present a case of vascular leiomyoma arising specifically from the floor of the nasal vestibule in a 68-year-old man, which is unique because it combines the specific tumour localization with the patient's gender. CASE REPORT: The patient was treated surgically. The tumour was completely removed through an intraoral incision. CONCLUSIONS: This is the first reported case of vascular leiomyoma arising from the floor of the nasal vestibule affecting a male patient.

OBJECTIVES: Schwannomas (neurilemmomas) are benign solitary tumours which arise from the Schwann cells of the neural sheath, most often from the VIII cranial nerve. Extracranially, 25% of all schwannomas are located in the head and neck. Intra-oral development is uncommon and a location in the tongue has been reported in individual cases. METHODOLOGY: We present a young patient with a schwannoma in the distal right side of the tongue. RESULTS: The tumour had grown slowly producing no symptoms. The diagnosis was made on histological examination. Surgical enucleation of the mass was uncomplicated and there was no recurrence. CONCLUSIONS: We report a further case of a schwannoma of the tongue, highlighting the need for this to be considered in the differential diagnosis.

BACKGROUND/AIMS: Gastric mucosal blood flow estimation in humans is obtained through an endoscope and the time of measurement lasts only a few minutes. Thinking that long-term monitoring of mucosal perfusion would be a significant contribution to the study of gastric physiology, we registered gastric mucosal blood flow continuously for 24 hours, using single fiber laser-Doppler technology. METHODOLOGY: The study was undertaken in 16 healthy subjects (8 of them had their gastric acidity inhibited with a proton pump inhibitor) and in 8 patients with an endoscopically proven, active duodenal ulcer. A 140 cm-long single fiber laser-Doppler microprobe was positioned through a gastrointestinal tube in the middle of the gastric corpus and the mucosal microcirculation was monitored from 14.00 h until 13.59 h the following day. Data were stored and processed to evaluate the probable circadian rhythms, using maximum entropy spectrum analysis. RESULTS: We found that the daily variations of gastric mucosal perfusion follow a circadian rhythm. The respective patterns with maximum and minimum values were: healthy controls, maximum at 02.00, 10.00, 18.00 h and minimum at 5.30, 14.00 and 22.00 h. Healthy controls treated by a proton pump inhibitor, maximum at 02.00, 07.00, 18.00 h and minimum at 04.00, 12.00 and 22.00 h. Ulcer patients, maximum 07.00 and 21.00 h and minimum at 17.00 and 24.00 h. CONCLUSIONS: It is concluded that long-term measurement of gastric mucosal blood flow in conscious humans is feasible and that this factor of gastric physiology follows a concrete circadian rhythm, which is not particularly influenced by acid inhibition, but is completely distorted in ulcer patients.

The presence of the Actinomyces usually is not determined by the common histologic examination of preparations of tonsillar tissue which has been removed surgically. The Actinomyces are common saprophytic microorganisms which are found inter alia in the oral cavity and palatine tonsils. In this study, the authors examined histologically 238 surgical preparations of tonsillar tissue. In 84 of these, that is 35.21%, it has been noted, except the others, the presence of Actinomyces israeli. At the same time, the authors state their views concerning the contribution of the Actinomyces of tonsillar crypts to the pathogenesis of chronic tonsillitis.

In the present treatise, a classification scheme for macroglossia has been formulated, based on clinical and etiological features of an enlarged tongue. The pathogenesis of each form-type of macroglossia is then described. In addition to, the authors report a case of female patient suffering from macroglossia, who was admitted in their Clinic. This pathological condition was the single and the very first clinical sign (symptom) of her, and (which) led up to the diagnosis of amyloidosis. They present the procedure of the diagnosis and differential diagnosis for this patient, they emphasize their conclusions (considerations) and make comments on the coexistence or correlation of macroglossia with amyloidosis.
