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.

Sebaceous hyperplasia (SH) is a proliferative abnormality of sebaceous glands, most often seen in elderly individuals. It consists of single or multiple, asymptomatic, small yellow papules with a central depression. The face is most commonly affected, but there have been reports of SH on the chest or genitalia. A lobular array of well-differentiated mature sebaceous lobules is noted on histological preparations. In this report, we describe a patient with SH on the penile shaft and parts of the scrotum.

Pigmentary demarcation lines are abrupt transition lines between the areas of deeper pigmentation and the areas of lighter, normal pigmentation. Type B pigmentary demarcation lines involve the posterior medial portion of the lower extremities and are more commonly associated with pregnancy. We present a case of pigmentary demarcation lines of pregnancy with erythematous changes, involving both the anterior and posterior aspects of the lower extremities.
