Actinic keratoses (AK) are premalignant lesions, which can develop into invasive squamous cell carcinoma(SSC). Therapies for AK include cryotherapy, curettage, topical 5-fluorouracil, laser therapy and so forth. All therapies currently prescribed can be painful and may result in scarring and changes in skin pigmentation. A potential new treatment modality for AK is the imiquimod (Aldara(R)), which can be applied by patients themselves. We reported a case of AK which was very extensive on the scalp of the old man, who was treated with topical imiquimod.

We report a case of intradermal nevus in a 43-year-old female patient, who presented with a tender, solitary papule on the periungual area, which seemed to be a periungual fibroma. The skin biopsy revealed the upper dermis and lower dermis containing nests and cords of nevus cells without junctional activity. It was totally removed by excisional biopsy.

Seborrheic keratoses (SK) are very common benign tumor arising in epidermis. Few malignant transformation of SK were reported. Inflammation, ulceration or atypical nature is the evidence of malignant transformation. Some melanoma can mimic SK. So, all SK need confirm histopathologic diagnosis. We reported a case of recurrent seborrheic keratosis with satellite lesions on the left groin in a linear pattern in a 46-year-old man.

Acrometastasis is rare and accounts for 0.1% of all metastasis. Renal cell carcinoma accounts for only 10% of this infrequent site. It is usually the late manifestation of a disseminated tumor, but may also be the primary manifestation of an occult cancer. Clinically, it may mimic benign tumors or nonneoplastic osteoarthritic conditions, thus resulting in misdiagnosis and improper treatment. We reported a case of acrometastasis in a renal cell carcinoma in a 76-year-old man who had been diagnosed with a progressed renal cell carcinoma with metastasis of the lung and brain.

PURPOSE: Glomus tumors are uncommon benign neoplasms arising from the neuromyoarterial apparatus, usually seen in the nail bed of fingers. Most of this mass presents typical symptoms such as severe pain, point tenderness and hypersensitivity to cold like neuroma, gout or causalgia. Concerning about the origin, there were few written reports about extra-digit glomus tumor, especially that occurred in the skeletal muscule. METHODS: A 48-year-old female complained of painful tender mass in her right calf aggravated several months ago. Her MRI and femoral angiogram showed a well defined hypervascular tumor such as hemagioma or hemagioendothelioma in the right calf. Surgical treatment was performed, and it proved glomus tumor in soleus muscle histologically. RESULTS: After the operation, patient didn't complain of her symptoms any more and there was no evidence of recurrence during 1 year follow-up period. CONCLUSION: Authors have found only eight cases of intramuscular glomus tumor reported in the literature and present here the ninth case of an intramuscular glomus tumor and first case of soleus muscle.

Leukemia cutis is the cutaneous involvement of leukemic neoplastic cells. It is an uncommon feature of systemic leukemia, and is associated with a poor prognosis. A 20-year-old man presented with a solitary, 2 cm dome- shaped, firm, erythematous nodule on the right medial malleolus that was present for 3 months. The patient had a history of venous catheter insertion at the right medial malleolus area 3 months previously. The history was significant for acute lymphoblastic leukemia (ALL) for 4 years; an allogenic bone marrow transplantation was performed 3 years earlier. The histologc examination of the lesion revealed diffuse infiltration of leukemic cells in the dermis and subcutis. Herein we report a case of leukemia cutis at the site of a prior catheter insertion in a patient with ALL
