Lymphoblastic lymphoma is a malignant neoplasm of precursor lymphocytes with a B- or T cell phenotype. T cell lymphoblastic lymphoma is a clinically aggressive disease with frequent involvement of extranodal sites, but the involvement of the skin is rare. The clinical appearance of skin lesions usually includes single or multiple papular or nodular lesions preferentially located on the head and neck. Herein, we report the case of a 31-year-old man presenting with skin involvement of T cell lymphoblastic lymphoma. The lesions manifested as asymptomatic, multiple, round, reddish brown macules, and patches on both extremities. Histology examination showed dense, diffuse infiltration of medium sized lymphoid cells into the entire dermis. The tumor cells had irregular nuclei, finely dispersed chromatin, inconspicuous nucleoli, scant cytoplasm, and expressed TdT, CD3 and CD5.

Focal myositis is a rare, benign inflammatory pseudotumor of the skeletal muscle of unknown etiology. In Korea, there is no case report of focal myositis, which is not combined with connective tissue disease. We present an unusual case of focal myositis with ankle contracture, involving more than two muscles. A 26-year-old man visited our clinic complaining of right ankle contracture and leg muscle pain. Physical examination revealed no muscle weakness or any other neurological abnormality. T2-weighted magnetic resonance imaging of the right leg demonstrated diffuse high signal intensity of the right gastrocnemius, flexor digitorum longus, and tibialis anterior muscles. Needle electromyography showed profuse denervation potentials with motor unit action potentials of short duration and small amplitude from the involved muscles. All these findings suggested a diagnosis of focal inflammatory myositis and the patient was put under oral prednisolone and physical therapy.

MCPP (2-(4-chloro-2-methyl phenoxy) propionic acid) is a phenoxy herbicide found in many household weed killers and lawn fertilizers. Some of the phenoxy acids, salts, and esters are moderately irritating to skin, eyes, and respiratory and gastrointestinal linings. In a few individuals, local depigmentation has apparently resulted from protracted dermal contact with phenoxy compounds. Although acute irritant contact dermatitis induced by herbicides is common, chemical burns induced by herbicides have been reported infrequently in the literature. Here we describe a chemical burn in a 25 year old female after sitting on a lawn that had been sprayed with MCPP 3 days earlier. This case illustrates potential hazards of the herbicide on the lawn of a public park.

BACKGROUND: Idiopathic calcinosis cutis (CC) is currently sub-classified as tumoral CC, sub-epidermal calcified nodules, idiopathic CC of the scrotum, and milia-like CC. This sub-classification system is obscure and can be confusing at times. OBJECTIVE: This study was designed to characterize the clinical and histologic features of idiopathic CC, to evaluate the adequacy of the current sub-classification system, and to propose a new sub-classification system. METHODS: Thirty patients with idiopathic CC were sub-classified according to the Lever classification and the Walsh and Fairley classification and were also categorized based on the type of the primary lesion. RESULTS: Idiopathic CC lesions were most common on the buttock (n=7), followed by the scrotum (n=5), arms and legs (n=5), hands and feet (n=4), inguinal area (n=3), ears (n=2), neck (n=2), trunk (n=1), and face (n=1). With the Lever classification, twenty-three of 30 cases were categorized as "unclassified". With the Walsh and Fairley classification, twenty-three cases were categorized as "unclassified", whereas with our new classification system, we managed to classify all cases as either nodular or papular calcification according to the type of the primary lesion. CONCLUSION: In this study, we identified a common location and the primary morphological features of idiopathic CC. Our findings suggest that our new sub-classification system based on the type of the primary lesion would be useful.
