Background:No ideal treatment has been established for Striae distensae (SD), particularly in the late phase (Striae Alba (SA)). Various types of lasers have been recently proposed as treatment options for SD. This study aims to compare the clinical efficacy of a fractional CO2 laser as well as a combination of fractional CO2 laser and Pulsed dye Laser (PDL) in the treatment of SA.Materials and Methods:Eighty-eight SA lesions in three female patients were included. Lesions on each half of the body were randomly enrolled in each group. Group 1 (n = 44) were treated by Fractional CO2 laser resurfacing and group 2 (n = 44) by a combination of PDL and Fractional CO2 laser, alternately. Digital Photographs were taken and the surface area of each lesion was measured digitally (using the PictZar Digital Planimetry Software) at the baseline and four weeks after treatment. The clinical improvement was assessed by comparison of the pre- and post-treatment photos and the participants’ views about their degree of improvement, using a 10-point verbal analog scale (VAS).Results:The mean surface area decreased significantly in both groups after treatment. The mean difference between the pre- and post-treatment surface area was 0.62 ± 053 for group 2 and 0.41 ± 0.43 for group 1 (P-value = 0.03). Mean VAS and dermatologist assessed improvement scale in group 2 (6.68 ± 0.77 and 2.2 ± 0.76 respectively) were significantly higher than those in group 1 (5.45 ± 0.90 and 1.8±0.72 respectively, P-value <0.001 and 0.04 respectively).Conclusion:The combination of PDL and fractional CO2 laser was more effective than fractional CO2 laser alone and could be suggested as a clinical option in the treatment of SA.

Pyoderma gangrenosum (PG) is an uncommon inflammatory ulcerative skin disease. It is characterized by painful progressive necrosis of the wound margins. Rarely, postoperative pyoderma gangrenosum (PPG) manifests as a severe disturbance of wound healing following surgical interventions. Only rare cases of this complication have been reported after appendectomy. We report a case of PPG in a 29-year-old female after appendectomy. She was successfully treated with oral prednisolone. Postoperative pyoderma gangrenosum should be kept in mind in the differential diagnosis of any postoperative delayed wound healing, because this disease is simply distinguished from a postoperative wound.

Background:Post inflammatory hyperpigmentation (PIH) is a common problem occurs following many dermatologic diseases and medical interventions. Different modalities including topical agents, lasers and intense pulsed light (IPL) are suggested for treatment of the post-burn PIH. In the current study, we evaluated the efficacy of IPL plus modified Kligman cream (MODIFIED KLIGMAN CREAM) versus MODIFIED KLIGMAN CREAM alone in the treatment of the post-burn PIH.Materials and Methods:This was a randomized, non-blinded clinical trial. A total of 53 patches of post-burn PIP in 14 patients were randomized to receive either two sessions of IPL plus modified Kligman formula or kligman formula for 2 months. The patients were recommended to apply MODIFIED KLIGMAN CREAM cream for 12 h at night.Results:According to our results, the patients in the MODIFIED KLIGMAN CREAM + IPL group had higher satisfaction as compared with MODIFIED KLIGMAN CREAM alone (P = 0.000) (Mann–Whitney test). In addition, according to physician evaluation, the patients in the MODIFIED KLIGMAN CREAM + IPL group had higher satisfaction as compared with MODIFIED KLIGMAN CREAM alone (P = 0.000) (Mann–Whitney test). No side effects except a little irritation, erythema and exfoliation due to MODIFIED KLIGMAN CREAM cream were seen in the patients.Conclusions:The results of our study showed the better efficacy and faster response of the IPL plus modified Kligman formula versus modified Kligman formula in the treatment of the post-burn PIH. To better determine the efficacy of IPL in treatment of the post-burn PIP, more extensive studies as randomized, double-blinded clinical trial are recommended.

Neonatal lupus erythematous (NLE) is a rare condition presented by lupus dermatitis shortly after birth or later following sun exposure. Sturge–Weber syndrome (SWS) is also an uncommon congenital condition characterized by extensive capillary malformation and ophthalmic and/or neurologic involvement. Here, we describe the first case of coexistence of NLE and SWS which posed a significant diagnostic challenge to clinicians.

Background Kaposi's sarcoma (KS) is a rare multifocal angiogenic tumor often seen in immunocompromised setting such as acquired immunodeficiency syndrome (AIDS) or organ transplantation recipients. Pemphigus vulgaris (PV) is a rare blistering disorder with mucocutaneous involvement for which immunosuppressive therapy has long been the core of treatment. Iatrogenic form of KS has been reported infrequently in pemphigus patients as a result of long‐term immunosuppressive therapy. Case We describe a 39‐year‐old male patient with confirmed diagnosis of PV who developed KS after receiving immunosuppressive agents for his pemphigus. KS was initially localized to the oral cavity with features mimicking exacerbation of his pemphigus. Conclusion This interesting case of KS suggests that dermatologists visiting patients with pemphigus with discomfort in the oral cavity should have a high degree of awareness and consider other differential diagnoses along with merely an exacerbation of PV.
