Use of touch preparation for rapid diagnosis of disseminated candidiasis

Bull's-eye cutaneous infarct of zygomycosis: A bedside diagnosis confirmed by touch preparation

“…Grossman et al reported the use of touch preparation using gram stain for the rapid diagnosis of disseminated candidiasis. 28 In our case, we were able to confirm the fungal etiology by rapid processing of the touch preparation with PAS stain within 45 minutes by our dermatopathology laboratory.…”

Touch preparation for the rapid diagnosis of disseminated aspergillosis

“…Although few cases are reported in the literature (Table I),7, 8 a touch preparation slide takes only a few minutes and may be a useful routine practice when taking skin biopsy specimens from immunocompromised patients. When secondary cutaneous invasive aspergillosis is suspected, it is crucial to ensure that tissue for touch preparation is recovered from the base of the biopsy section.…”

A Method of Assessing the Adequacy of Trucut Biopsy Specimens Obtained with a 19-Gauge Trucut Core Biopsy Needle

“…[14][15][16][17][18] Touch-preps of core biopsies of abdominal organs have been shown to be as accurate as FNA smears while providing features of tumor architecture. 19 We have now demonstrated that TCB specimens obtained using the Quick-Core needle can be evaluated by making touch-preps while preserving enough core material for subsequent histologic analysis.…”
