Vitiligo is a result of disrupted epidermal melanization with an undecided etiology and incompletely understood pathogenesis. Various treatment options have resulted in various degrees of success. Various surgical modalities and transplantation techniques have evolved during the last few decades. Of them, miniature punch grafting (PG) has established its place as the easiest, fastest, and least expensive method. Various aspects of this particular procedure have been discussed here. The historical perspective, the instruments, evolution of mini grafting down the ages, and the methodology, advantages, and disadvantages have been discussed. A detailed discussion on the topic along with a review of relevant literature has been provided in this article.

“…Pathogenetically, positive sometimes pustular patch tests are demonstrated in over 50% of cases and provide indirect evidence of an underlying immunological process involving T cells [13,14,15,16]. The crucial role of T cells is additionally supported by positive lymphocyte transformation test results as has recently been shown by Beltraminelli et al [unpubl.…”

Ciprofloxacin-Induced Acute Generalized Exanthematous Pustulosis Mimicking Bullous Drug Eruption Confirmed by a Positive Patch Test

We report the case of an 80-year-old woman presenting with ciprofloxacin-induced acute generalized exanthematous pustulosis (AGEP) confirmed by a positive patch test. Cutaneous morphology, course and histological findings were consistent with a definite diagnosis according to the AGEP validation score of the EuroSCAR study group. We point to the rarity of quinolone-induced AGEP and discuss immunological mechanisms, the value of in vivo and in vitro tests as well as the main differential diagnosis. Furthermore, we highlight in this particular case the challenging differentiation from bullous drug eruption.

“…Various hypotheses have tried to explain the pathophysiology of this phenomenon, claiming structural or microenvironmental changes in the spared skin. Knowing the diversity of conditions implicated in the different cases reported (table 1) [2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32], the mechanisms implicated might be multiple and complex.…”

The ‘Sparing Phenomenon' of Purpuric Rash over Tattooed Skin

Cutaneous complications associated with decorative tattooing are well known. However, the inhibition of a purpuric reaction by a tattoo is a fact that, as far as the authors know, has not been described before, fitting the definition of a ‘sparing phenomenon', the absence of manifesting a particular skin disease in an area previously affected by another condition. From the clinical observation of purpuric lesions apparently inhibited by a tattoo in a 26-year-old patient, we performed an exact binomial test on the observed and expected proportion of purpuric lesions inside (0%, 95% confidence interval, CI, 0-2.6%) and outside (100%, 95% CI 97.4-100%) the tattooed skin, demonstrating a nonrandom distribution respecting the tattooed area (p < 0.001) and identifying the composition of the ink used in the tattoo (color pigment, glycerine, Hamamelis virginiana extract, water and alcohol). Moreover, we reviewed the cases of sparing phenomenon described in the literature. In conclusion this is the first report of a sparing phenomenon of purpuric lesions over tattooed skin.
