(b) Red, tense, and semitranslucent appearance of a smooth tumor on the lower leg. (c) New-formed, hypertrophic-scar-like papules and plaques on the lower leg when PTM was active at the healing wound site after trauma and suture. (d) An arrow indicated new-formed papules and plaques on the active lesions of PTM on the lower leg. (e) Arrows indicated new-formed, red papules on the active lesions of diffuse swelling variant at the lower legs. (f) An arrow indicated tense, pearl-like papule and nodule on the active elephantiasis with dry, papillary appearance on the lower legs. (g) An arrow indicated irregular, scarlet, and swelling erythema on the legs when PTM recurred.
