Leukemia cutis, skin lesions in leukemia, are clinically divided into specific and nonspecific types. Specific skin lesions demonstrate malignant cell infiltrate when the biopsy is done. We have encountered a typical case of specific skin lesions of leukemia cutis associated with acute lymphocytic leukemia in a 18-year-old male patient. There were multiple, pinhead to rice sized, skin colored to lemon yellow colored, discrete papules on the face, neck and trunk. A review of the literature is presented with a brief discussion of this case.

Histiocytic medullary reticulosis is a rare, uniformly fatal, acute disease of the reticuloendothelial system. The disease is associated with fever, malaise, weakness, weight loss, lymphadenopathy, hepatosplenomegaly, jaundice, and purpura. Common laboratory findings are severe anemia, leukopenia, and thrombocytopenia. A 49-year-old male patient is described who had multiple purple nodules and tumors in the skin. A biopsy taken from a skin lesion showed a diffuse proliferation of atypical histiocytes in the dermis and subcutaneous tissue.However, erythrophagocytosis of these atypical histiocytes was not seen.

Electron microscopic examination of specimens from lesions of eight patients with hyperpigmented and six patients with hypopigmented tinea versicolor and from unaffected skin in each patient was performed. The results are summarized as follows; 1. In hyperpigmented lesions, melanosomes are larger and more singly dispersed than in unaffected skin. 2. In hypopigmented lesions, melanosomes are smaller and less singly diepersed than in unaffected skin. 3. Number of total melanosomes in hyperpigmented and hypopigmented lesions was not different from in unaffected skin.

Cryptococcosis is an acute, subacute or chronic infectian caused by the encap sulated yeast Cryptococcus neoformans. The case of Cryptococcosis is a 2 5/12 year-old boy with involvement of the skin, lungs, liver, spleen, lymph node and central nervous system is reported. He has suffered from fever, nausea., vomiting and multiple skin lesions for a month. Thcre were various cutaneous lesions consisting of papules, pustules, nodules, crusts and ulcers on the scalp, face, back, buttocks and both extremities. Diagnosis was confirmed by the clinical characteristics, histopathologic findings and culture of the C. neoformans from cerebrospinal fluid and marcerated skin tissue. He was successfully treated with combination of Amphotericin B and 5-fluorocytosine.

Purpose:
Survival probability changes over time in cancer survivors. This study examined conditional survival in patients undergoing curative resection for non-small cell lung cancer (NSCLC).
Materials and Methods:
Five-year conditional recurrence-free survival (CRFS), conditional overall survival (COS), and conditional relative survival (CRS) up to 10 years after surgery were calculated in patients who underwent NSCLC resection from 1994 to 2016. These rates were stratified according to age, sex, year of diagnosis, pathological stage, tumor histology, smoking status, comorbidity, and lung function.
Results:
Five-year CRFS increased from 65.6% at baseline to 90.9% at 10 years after surgery. Early differences in 5-year CRFS according to stratified patient characteristics disappeared, except for age: older patients exhibited persistently lower 5-year CRFS. Five-year COS increased from 72.7% to 78.3% at 8 years and then decreased to 75.4% at 10 years. Five-year CRS increased from 79.0% at baseline to 86.8% at 10 years. Older age and higher pathologic stage were associated with lower 5-year COS and CRS up to 10 years after surgery. Female patients, those with adenocarcinoma histology, non-smokers, patient without comorbidities and had good lung function showed higher COS and CRS.
Conclusion
CRFS improved over time, but significant risk remained after 5 years. CRS slightly improved over time but did not reach 90%, suggesting significant excess mortality compared to the general population. Age and stage remained significant predictors of conditional survival several years after surgery. Our conditional survival estimates should help clinicians and patients make informed treatment and personal life decisions based on survivorship status.
