Quantifying Skin Disease Burden in Mycosis Fungoides–Type Cutaneous T-Cell Lymphomas

“…In addition, erythema scores that separate barely detectable, readily detectable, and marked and maximal erythema are not easily and consistently distinguishable. In contrast, observers of skin disease can readily distinguish lesion types: patch, plaque, and tumor or ulceration 11 factors reflect the histologic depth of infiltration 12 and are thereby valid measures of disease burden or severity. Finally, the severity of erythema, scaling, or induration may vary in intensity relative to the other two.…”

SPOROTRICHOSIS (A Case Report)

“…Clinical picture and histopathological findings in this case were highly suggestive of sporotrichosis and which was further confirmed by remarkable therapeutic response to potassium iodide administration. The lack of demonstration of fungal cclls in biopsied tissue as seen in our case is not an uncommon feature [6], Potassium iodide is still the treatment of choice in cutaneous sporotrichosis [2]. Sporotrichosis is the only mycosis in which curative power of potassium iodide is beyond dispute [1].…”

“…Sporotrichosis manifests as fixed cutaneous, lymphocutaneous, disseminated cutaneous and systemic forms [6]. Lymphocutaneous from is the commonest presentation [1] and upper extremity is the site commonly involved [2,4].…”

Lupus vulgar: caso infrecuente de tuberculosis extrapulmonar

“…En 40% existe linfadenitis tuberculosa asociada y en 10-20% coexistencia con TB pulmonar u ósea 1 . El estudio histológico evidencia granulomas tuberculoides en la dermis superior, es frecuente encontrar alteraciones secundarias como atrofi a, ulceración, acantosis e hiperplasia pseudocarcinomatosa 15 . El bacilo es difícil de encontrar por lo que los cultivos son generalmente negativos; sólo 6% de los cultivos son positivos 7 .…”
