Carcinoid tumors are the most common endocrine tumors of gastrointestinal tract. Argentaffin cells are the origin of carcinoids. These cells belong to the amino precursor uptake and decarboxylation (APUD) system. These cells give the tumor its most distinguishing feature: the ability to produce biogenic amines and polypeptide hormones that, in turn, give rise to the dramatic carcinoid syndrome. We treated a case of multi-centric carcinoid tumor of the duodenum in a 63-year-old male patient. He was admitted to the hospital because of epigastric pain. On the gastrofiberscopic examination, 1.0 x1.5 cm and 0.7 x0.8 cm sized two polyps (Yamada type II, I) were noticed on the duodenal bulb. The biopsy specimen showed carcinoid tumors of different histologic types. The level of 24-hour urine 5-HIAA of this case was normal. He was treated with subtotal gastrectomy with Billroth-II anastomosis. We report this case with literature review.

Castleman's disease is a benign disorder characterized by hypervascular lymphoid hyperplasia. The etiology of the disease is still unknown. Although it may occur at the various sites such as peritoneum, retroperitoneum, pelvic lymph node, muscle and lung, it occurs most commonly at the mediastinum. Even though specific pathophysiologic relations are still not clearly determined between two different histologic types -hyaline vascular type and plasma cell type-, there were several previous reports dealing with the plasma cell type transformed or progressed into different types of malignancies such as malignant lymphoma, Kaposi's sarcoma and Hodgkin's disease. We experienced a case of plasma cell type Castleman's disease that transformed into a malignant lymphoma and report this case with review of literatures.

BACKGROUND: The need for dermatological consultations for hospitalized patients has gradually increased and there are a number of dermatoses caused by underlying psychological conditions. However, the data regarding the analyses of these consultations for psychiatric inpatients are limited. OBJECTIVE: To analyze the demographics and the type of dermatoses among inpatients with primary psychiatric diseases. METHODS: We retrospectively reviewed 581 consultation reports for inpatients referred by the Department of Psychiatry between January 1, 2009 and December 31, 2014. RESULTS: The proportion of the consulted patients from the Department of Psychiatry was 25.9% (331 consulted inpatients/1279 psychiatric inpatients). The most common age group was the 40~49 year-old group (19.3%) and the male to female ratio was 1:1.14. There were no remarkable findings regarding the annual or seasonal distribution. According to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), the most common underlying psychiatric disorders were mood disorders (41.0%), followed by schizophrenia and other psychotic disorders (25.0%), and substance-related disorders (12.1%). The most frequent skin disorders were eczematous dermatoses (34.6%) and infectious dermatoses (32.2%); dermatomycosis (20.8%) was especially common. The most common reasons for consultation were new-onset dermatologic problems (68.5%), followed by persistence or aggravation of pre-existing dermatologic disorders (28.7%). CONCLUSION: This study reports the dermatologic characteristics of psychiatric inpatients. We conclude that dermatologists and psychiatrists need to be concerned about the education and continuous management of various skin diseases in psychiatric patients.

The mucus secretion of airway glands is known to be controlled by the various autonomic neurotransmitters such as noradrenalin and acetylcholine. However, a recent study suggests that non-adrenergic, non-cholinergic (NANC) nerves may contribute to the secretory activity of glands. Substance P (SP) has been proposed as a neurotransmitter of the NANC nervous system. SP is present within nerve fibers innervating the airway mucosa and is known to be released from sensory nerves via an axonal reflex. SP activity is controlled by neutral endopeptidase (NEP) which degrades SP. In this study, we evaluated the effects of NEP inhibitor (thiorphan) and substance P on nasal mucosa and histamine on the nasal mucosa in healthy males. In the thiorphan-substance P experimental group, the nasal volume decreased after nebulization of substance P in proportion to the concentration of histamine. In the thiorphan-substance P experimental group, the frequency of sneezing increased in proportion to the concentration of histamine, but there was no increased frequency of sneezing from thiorphan, SP and normal saline. The results of this study suggest that axonal reflexes can play a role in the pathogenesis of nasal mucosal hypersensitivity and neurogenic inflammation.
