Secondary cutaneous cryptococcosis may occur earlier than other manifestations of disseminated cryptococcosis. A 68-year-old woman presented with multiple ulcerative lesions on the right calf of 2 weeks duration. She had been treated with antibiotics, but the lesions spread rapidly. The initial clinical impression was necrotizing fasciitis, but routine KOH mounting from the ulcerative lesions showed numerous budding yeast cells with peripheral clear zones and further investigations including a skin biopsy, tissue cultures and India ink preparations allowed a rapid and definitive diagnosis of cutaneous cryptococcosis. Studies for other evidence of infection elsewhere revealed an asymptomatic pulmonary lesion. We report a case of secondary cutaneous cryptococcosis clinically mimicking necrotizing fasciitis that occured before other manifestations of disseminated cryptococcosis.

A 28-year-old man presented with a 6.0 * 5.0 cm sized ulcer on the anterior chest and widespread copper-red colored maculopapular eruptions. There was no past or family history of syphilis sign or STS. He had been taken imposition of hands twice to treat chronic hepatitis about 4 months prior to presentation. Thereby, the ulcerative lesion on the anterior chest developed as a result of erosive trauma through contact with infected fingernails. The clinical features and serologic tests as well as biopsy findings were consistent with syphilis. Spirochetes were observed under the dark field examination of the anterior chest lesion. On Warthin-Starry staining, spirochetes were identified in the epidermal area of the papular lesion. We report a case of unusual transmission of syphilis.

While renovating our traditional medical curriculum to integrated curricular system in 1996, we planned to introduce a course of problem-based learning (PBL) on tutorial basis after finishing 14 courses of the integrated medical curriculum for two years. One tutorial group was composed of one tutor and eight students, and 105 students of the second grade were divided into thirteen small tutorial groups. The period of PBL course was two weeks from December 1 to 14 in 1997. There were three interrelated steps for design of PBL course: course preparation, implementation, and evaluation which were conducted by PBL subcommittee consisted of nineteen teachers. Students were exposed to four clinical case modules, and they met in small tutorial room three times per week for two weeks. The PBL programme was evaluated by questionnaire survey method at the end of PBL course. We obtained satisfactory and positive results from reply of faculty and students. Since many teachers participated in planning, implementing, and evaluation of PBL, we could accumulate lots of knowledge and skills regarding the PBL, and it was a good opportunity to train expertise for PBL, test the feasibility changing to PBL curriculum. At this moment, our present integrated medical curriculum will be gradually converted to PBL system totally, and our experience will provide a good aid for other medical schools appling traditional medical curriculum to introduce PBL in their medical education.

Nevus sebaceus is a common hamartoma that has a variety of appendage tumors. We report a case of nevus sebaceus with multiple appendage tumors on the scalp of a 43-year-old male. The exudative inflamed patches were admixed with darkly pigmented small nodules which had developed secondarily within a 4.0 × 1.5cm lesion 2 years previously. Histologically, on serial sectioning, there were various types of basal cell carcinoma, syringocystadenoma papilliferum, tubular apocrine adenoma and sebaceous adenoma. Some parts of a biopsy specimen, showed a tumor of the follicular infundibulum-like epidermal changes. There were also calcium depositions in the stroma and apocrine tumors, There was no relapse at 1-year follow-up after surgical treatment.

Cutaneous metastasis from renal cell carcinoma is not unusual, occurring in 3 to 7%, although it may be overlooked. We report a case of metastatic renal cell carcinoma in a 74-year-old man who was presented with a 1.5 x 1.5 x 0.5 cm-sized nodule on the right zygoma for 3 months. A skin biopsy demonstrated the typical clear cell adenocarcinoma with PAS(+) granules in the cytoplasm and honeycombed or glandular configuration, compatible with metastatic renal cell carcinoma. Kidney ultrasonogram and abdomina1 CT scanning showed a large cystic mass on the upper pole of the left kidney. Furthermore radiologic studies revealed multiple metastatic lesions in the lung, liver and brain. He died 4 months later.

To suggest a reasonable isometric point based on the anatomical consistency of interosseous membrane (IOM) attachment in association with topographic characteristics of the interosseous crests, the footprints of the central band (CB) of the IOM on the radial and ulnar interosseous crests (RIC and UIC) were measured. Methods: We measured the distance from the CB footprints from each apex of both interosseous crests in 14 cadavers and the angles between the forearm axis of rotation (AOR) and the distal slopes of the RIC and UIC in 33 volunteers. Results: The CB footprints lay on the downslope of both interosseous crests with its upper margin on average 3-mm proximal from the RIC’s apex consistently in the radial length, showing normality (p>0.05), and on average 16-mm distal from the UIC’s apex on the ulna without satisfying normality (p<0.05). The average angle between the UIC’s distal slope and the AOR was 1.3°, and the RIC’s distal slope to the AOR was 14.0°, satisfying the normality tests (p>0.05), and there was no side-to-side difference in both forearms (p<0.05). Conclusions: The CB attached to the downslope just distal to the RIC’s apex constrains the radius to the UIC that coincides with the AOR of the forearm circumduction, maintaining itself both isometrically and isotonically.

Radial nerve entrapment or compression in the upper extremity is relatively rare compared to medial nerve or ulnar nerve entrapment and compression. Various syndrome types are defined according to the location of radial nerve entrapment and the pattern of symptom expression. In the upper arm, Saturday night palsy or honeymoon palsy occurs. Around the elbow, posterior interosseous nerve entrapment syndrome, which involves pure motor symptoms, and radial tunnel syndrome, which mainly involves pain symptoms, can develop. Finally, superficial radial nerve entrapment occurs in the distal forearm and has the symptom of painful or abnormal sensory disturbances of the hand. Conservative treatment is usually the first choice for radial nerve neuropathy, unless there is motor paralysis. Surgical treatment can be considered if there is no improvement after adequate conservative treatment.

The macrocystic form of serous cystadenoma of the pancreas is an uncommon benign neoplasm composed of few, relatively large cysts that are lined by uniform, glycogen-rich, cuboidal epithelial cells. We report here on two cases of pathologically proven macrocystic serous cystadenoma of the pancreas in a 45-year-old female patient and a 53-year-old female patient. Both these cysts were lined by low cuboidal epithelia without any evidence of mucin production. There was also no evidence of pancreatitis. These tumors were radiologically suspected as being mucinous cystic neoplasm or pseudocysts. Although the microscopic and immunohistochemical studies of the macrocystic variant are not different from the conventional serous microcystic cystadenoma, their unusual macroscopic features can lead to confusion for the clinicians and radiologists.

A 41-year-old woman was presented with dusky-red colored, multiple subcutaneous infiltrative plaques of varing size(3-15cm in diameter) on both lower legs, the right ankle and the left antecubital area for about 6 months. Although she complained of sensory disturbance on the skin lesions which led to suspect lepromatous leprosy, there was no evidence of leprosy. Skin biopsy specimens showed dense small and medium-sized atypical lymphoid cell infiltrates in the subcutis, with a mixed septal and lobular pattern and a few scattered hemophagocytic cells. Angioinvasion and angiodestruction were seen in the focal area of deep dermis. Immunohistochemistry displayed positive reactions to LCA, CD3 and UCHL-1, but negative to CD20 and CD30. EBV antigen on the tissue was positive. The clinicopathologic features were consistent with subcutaneous panniculitic T-cell lymphoma.
