Does solitary morphoea profunda progress?
Solitary morphoea profunda (SMP) is an unusual form of scleroderma and is rarely mentioned in the literature. The back of the trunk is described as the commonest site of involvement by SMP. This disease has been recognized as a nonprogressive condition. We report three cases of SMP seen at our department within a 1-year period. Interestingly, all three patients were females and the lesions were situated on the right upper buttock. In one patient the lesion extended despite using topical tacrolimus but subsequently the lesion was kept under control with topical clobetasol propionate.

Hair darkening in porphyria cutanea tarda.
Repigmentation of grey hair is rare, but has been described in several clinical settings. It has most often been reported as a postinflammatory effect, but several drugs, chronic arsenic exposure and coeliac disease have also been cited in addition to darkening as a spontaneous phenomenon. We report two patients with sustained repigmentation of the hair in association with porphyria cutanea tarda. The mechanism for this repigmentation remains elusive, but presumably involves recruitment of outer root sheath melanocytes, which are then activated to form functional hair bulb melanocytes.
