For pharmacometricians, probability theory is the very first obstacle towards the statistics since it is solely founded on mathematics. The purpose of this tutorial is to provide a simple version of introduction to a univariate random variable, its mean, variance, and the correlation coefficient of two random variables using as simple mathematics as possible. The definitions and theorems in this tutorial appear in most of the statistics books in common. Most examples are small and free of subjects like coins, dice, and binary signals so that the readers can intuitively understand them.

Tumor of follicular infundibulum is the term coined by Mehregan and Butler in 1961 for a benign hyperplastic lesion that extends from the follicular infundibulum as an epithelial plate with underlying elastic fiber network. This tumor appears as a slightly elevated keratotic lesion and is characterized histologically by proliferation of follicular sheath epithelium in the form of a thin subepidermal plate. We present a typical case of tumor of follicular infundibulum in the left shoulder area of 74 year-old-man. To the best of our knowledge, this is the first reported case of a solitary tumor of follicular infundibulum in Korea.

We report a case of a morphologic variant of dermatofibroma. A coin sized, brownish, shinny, somewhat fibrotic pedunculated tumor in a 39-year-old male was diagnosed as a sclerosing hemangioma, a type of dermatofibroma histopathologically. Its dome shape morphology was unusual in comparison with the typical morphology of dermatofibroma that we know.

The term 'isotopic response' was coined by Wolf to describe the emergence of a new skin disease at the site of another, unrelated, and already healed skin disease; most commonly herpes zoster. In the dermatologic literature, although a number of cutaneous lesions have been observed to develop at the site of healed herpes zoster, chronic cutaneous graft-versus-host reaction has been rarely reported. We herein report two cases of chronic cutaneous graftversus-host reaction which clinically presented as an isotopic response.

Aneurysmal bone cyst is a rare, non-neoplastic condition, which was first coined by Jaffe and Lichtenstein in 1942. Clavicle is an unusual site for aneurysmal bone cyst. Authors present a case of aneurysmal bone cyst which was found in the right clavicle of a 5 years old boy, because of its rarity of site of predilection.

The size of the cisterna magna is still detatable. Robertson13) stated that the cisterna magna varies greatly in capacity and described the large cisterna magna as a separate entity. He also found that in most cases the cisterna magna extended approximately 2.5cm above the foramen magnum and was usually 5mm deep with a variable width. Liliequist8) proposed a mean heigh of 28mm for the normal cisterna magna with a wide variation of 15 to 60mm, and a depth of 6mm at the foramen magnum with a variation of 2 to 10mm:however, he did not quote measurements for the width. Gonsette, et al.5) reported 28 cases of enlarged cisterna magna diagnosed by ventriculography and coined the phrase "mega grande citerne" or mega cisterna magna. All of these cases, however, had symptoms of posterior fossa disease. Our study of the syndrome of the mega cisterna magna without specific syndrome is presented nystagmus, transient syncope in the first & third cases were operated under suboccipital craniectomy and was confimed the large cisterna magna. This paper presents the clinical diagnosis with vertebral angiogrraphy, pneumoencephalography and computed tomography.

A 38-year-old female patient presented dystrophic nail changes on her all finger and toe nails for 10 years. On examination, nails were uniformly affected with longitudinal ridging, loss of normal luster and brownish discoloration. This patient has not had any inflammatory skin diseases or systernic illness for the past 10 years. Biopsy examination from the dystrophic nail showed non-specific eczematous changes. The clinical and histologic features of this yatient was considered as the consistent findings with the ty enty-nail dystrophy, occured on the idiopathic base, coined by previous authors.

Tuberous sclerosis (TS) is a complex genetic disorder characterized by the formation of multiple hamartomas. It was first described by von Recklinghausen in 1862. In 1880, Boumeville coined the term sclerose tubererse. In 1908, Vogt emphasized the classic triad of seizures, mental retardation, and adenoma sebaceum. TS is inherited as an autosomal dominant trait with a high incidence of sporadic cases. TS might be a relatively common disease, but familial cases were not reported commonly in neurological field. We reported a familial TS in brothers with protean clinical expressivity.
