Full history/Diagnosis is available below
Hyperhidrosis occurs as either a generalized or localized phenomenon. Localized hyperhidrosis most frequently involves the palms, soles, and intertriginous areas (i.e., axillae, inguinal folds, and perineal areas). Most localized cases are secondary to emotional stimuli. Less common causes include tabes dorsalis, hemiplegia, and unilateral nerve disorders.
The mechanism for such substantial Tc-99m MDP secretion in sweat is unknown. Sweat contains trace quantities of phosphate, but significant concentrations of chloride. It is possible that Tc-99m MDP is secreted by sweat glands in a fashion similar to phoshphate ion. Alternatively, Tc-99m pertechnetate may be handled similar to chloride ion by the sweat glands, and this could be the radiochemical form of the tracer. Tc-99m pertechnetate excretion is felt to be unlikely in this patient because of the absence of activity within the salivary glands, thyroid, or stomach.
