Acral lentiginous melanoma is a rare variant of malignant melanoma and is characterized by a lentiginous (radial) growth phase that evolves over months or years to a dermal (vertical) invasive stage. Clinical and pathological features were reviewed in 3 cases of acral lentiginous melanoma of the soles. The first case was a 59-year-old female. On gross examination, there was a black, nodular, round, and ulcerated mass, 1.5 x 1.5 cm, on the posterior portion of the left sole. This mass was accompanied by peripheral pigmented macules. Histologically, the macular lesion revealed the pattern of a lentiginous growth phase, with a diffuse hyperplasia of atypical melamocytes in the basal layer of the epidermis. In the vertical growth component, atypical melanocytes (predominantly spindle cell) infiltrated the dermis, showing level 3 invasion. The second case was a 47-year-old male. On gross examination, there was a dark brown to black, nodular, hemorrhagic and ulcerated mass, 7x7 cm, on the middle portion of the right sole. This mass grew radially into neighboring tissue. Histologically, the radial growth component revealed atypical melanocytes which were distributed in the basal portion of epidermis. In the vertical growth component, atypical melanocytes (spindle, round, or polygonal cells) infiltrated the dermis, showing level 4 invasion. The third case was a 87-year-old female. There was a formation of satellite pigmented macules, up to 2x0.5 cm, on the right sole. The color of macules was usually not uniform but was likely to be scattered radially, being grayish brown, bluish black, or black. Histologically, the peripheral, macular, hyperpigmented lesion revaled the pattern of a lentiginous growth phase. In the vertical growth component, atypical melanocytes (predominently polygonal cells) infiltrated the dermis, showing level 13 invasion.

Hibernoma is very rarely encountered and is expressed in the various names including "lipoma of brown fat", "fetal lipoma", and "lipoma of embryonic fat". In our knowledge, only about 50 cases have been reported in the literature of the Western world, and no case reports have been published in Korea. In May 1986, we experienced a case of hibernoma occuring in a 16 old years boy. On physical examination, a relatively well defined nodule was noted on the right scapular region. A total removal of the lesion was done under the clinical diagnosis of epidermal inclusion cyst. On gross examination, the specimen consists of three irregularly shaped portions of yellowish brown soft tissue, measuring up to 0.8 cm in greatest dimension. Microscopically, the tumor showed distinct lobular pattern separated by fibrovascular bands. The lobules were composed of multivacuolated or eosinophilic granular cells showing centrally located small unclei. A brief review of the literature was done.

Most spine surgeons and anesthesiologists believe that the risk of spinal cord injury (SCI) during intubation is mainly due to mechanical compression of the spinal cord due to cervical spine movement in cases of undiagnosed but severe cervical lesions. With this reasoning, difficult intubation, which is more frequently encountered in patients with preexisting cervical diseases, is likely to result in SCI. Several reports have described SCI after non-cervical surgery in patients previously diagnosed with cervical myelopathy and a chronically compressed cervical cord; however, to date, there is less acknowledgement of SCI in patients with undiagnosed cervical myelopathy. Here, we report a painful experience of neurological deterioration that developed immediately after elective lumbar decompressive surgery in a 76-year-old man. The possible mechanism behind these unexpected complications is discussed in a review of the literature.

BACKGROUND AND OBJECTIVES: Laminins are extracellular matrix proteins localized mainly in basement membranes. Currently there are at least ten different laminin chains and 11 heterotrimetric laminin variants. Laminin-5 is a heterotrimeric basement membrane molecule (alpha3beta3gamma2). It serves as an important adhesion protein for epithelial cells and it also plays an important role in cell migration during tumor invasion and tissue remodeling. This study was designed to investigate the relationship between laminin-5 expression and clinicopathologic variables in oral cavity and oropharynx squamous cell carcinomas using immunohistochemistry. MATERIALS AND METHOD: The expression of the laminin-5 around tumor cells was determined in 32 oral cavity and oropharyngeal carcinomas by immunohistochmical staining with antibody against laminin-5gamma2 chain. RESULTS: Statistical analysis showed that the frequency of laminin-5gamma2 chain expression was correlated with the lymph node metastasis (p<0.05). The poor differentiation of tumor cells, the large tumor size, advanced overall stage and the deep tumor invasion showed high expression of laminin-5, although it was not significant statistically. CONCLUSION: These results suggest that overexpression of laminin-5 in oral cavity and oropharyngeal squamous cell carcinoma might be a biomarker that can predict cervical lymph node metastasis.

Lymphoid tumors of the orbit are rare, and sometimes it is not possible either clinically or histologically to differentiate between lymphoid tumor and pseudolymphoma. Some authors assert that the degree of cytologic differentiation appears to be the single most important factor for determining the prognosis of patients with orbital lymphoid lesions. However, the cytomorphologic basis is not so helpful to diagnose and classify our case, which shows some discrepancy between pathological findings and clinical and radiological findings. At first we misdiagnosed our case as orbital malignant lymphoma on the basis of cytomorphology and immunohistochemical study. But no responce to local intensive radiotherapy and the follow up study of the patient suggest orbital pseudolymphoma.
Follow-Up Studies

Calcific tendinitis of the shoulder joint is common disease causing acute pain, mainly involving the supraspinatus or infraspinatus muscle, and less frequently the teres minor or subscapularis muscle. This study reports on the satisfactory arthroscopic removal of calcium deposits as well as infraspinatus and supraspinatus muscle repair without relapse via minimal incision using suture anchors. This was a case of atypically extensive calcific tendinitis involving the infraspinatus muscle, with a bursal side partial rupture of the supraspinatus muscle in a 61-year-old female whose chief complaint was chronic pain of the right shoulder exacerbated by limited movement.
