Abstract
Pyoderma gangrenosum is among the exceptional extra‐intestinal manifestations of celiac disease. We report a case of a 52‐year‐old patient who presented with pyoderma gangrenosum that turned out to be the initial presentation of celiac disease. We report a case of a 52‐year‐old patient who presented with pyoderma gangrenosum as initial presentation of celiac disease. We highlighted the importance of considering cutaneous manifestations in celiac disease patients presenting in adulthood.

Abstract
Since pemphigus blisters are intraepidermal, scarring should induce at most a post‐inflammatory hyperpigmentation. We describe a very atypical and unusual course of pemphigus vulgaris with extensive keloid formation despite high systemic steroids. This could be promoted by the severe flare of the disease, the delay of scarring, and the superinfection.

Abstract
A 4-year-old boy born from a consanguineous marriage was referred to our department for congenital ichthyosis. He was a collodion baby at birth and progressively developed a generalized erythroderma with fine whitish scales covering his body. Initially, he was diagnosed as having congenital ichthyosiform erythroderma. Physical examination revealed fine white grayish scales with an erythematous background involving the scalp and flexural areas (Figure 1a). His palms and soles depicted hyperlinearity (Figure 1b). His hair, teeth, nails, and mucosa were normal. Abdominal examination revealed hepatomegaly, and the liver was enlarged by 4 cm below the right costal margin. He had a normal motor and mental development, and his neurologic examination was normal. There was no muscular weakness. (SKINmed. 2022;20:305-306).

Abstract
Autosomal recessive congenital ichthyosis (ARCI) is a clinically and genetically heterogeneous category of non-syndromic ichthyosis (2). Nail changes in ARCI are generally frequent but have been rarely reported and studied in the literature. This stimulated us to conduct a study to describe nail changes in ARCI using a combined literature review and prospective examination from March 2019 to August 2019 (6 months) in the Dermatology Department of Habib Thameur Hospital, Tunis, Tunisia. A total of twenty-five patients with ARCI had a clinical and dermatoscopic review. Mean age was 19.8 years old [range 1-43], with a female predominance- 17 women (68%) and 8 men (32%). Seventy-two percent had nail unit changes involving more than one nail, none with single nail disease, involvement of fingernails (64%) and toenails (68%) cases including periungual hyperkeratosis (64%), xanthonychia (40%), pachyonychia (40%), macrolunula (36%), digital clubbing (32%) and onychomycosis (24%). Rarer findings included pseudoainhum, transverse leukonychia, longitudinal melanonychia, and subungual hemorrhages each in one patient (4%). There was a statistically significant increased frequency of nail changes in adults over children (p = 0.001). Nail abnormalities statistically associated with ARCI were macrolunula, periungual hyperkeratosis, xanthonychia, and pachyonychia. A comprehensive review of the literature was performed, creating the first comprehensive review addressing nail disease in ARCI.

Abstract
Acquired digital fibrokeratoma is a rare and benign fibrous tumor; it is usually asymptomatic, and frequently arises from the fingers. The diagnosis is easily confirmed by pathologic evaluation. However, in some cases, it may be misdiagnosed as other benign conditions, mainly adnexal tumors and common warts, especially when located on the foot and toes. In this article, we report the case of a 45-year-old man who presented to our clinic for an acquired growth over the plantar surface of the second right toe. The tumor had evolved for 1 year and affected the patient's activities and mobility. On examination, the lesion was a dome-shaped, firm tumor with keratotic distal changes and a broad base attached to the overlying skin. Pathologic assessment was consistent with the diagnosis of acquired digital fibrokeratoma, ruling out other causes of abnormal growth. The tumor was completely excised with surgery, with excellent outcomes and no recurrence at follow-up. Although acquired digital fibrokeratoma is a rare condition, mostly located on the distal upper extremities and fingers, it should be considered in the differential diagnosis of plantar soft-tissue tumors. Surgical management remains the mainstay of treatment.

Abstract
Earlobe keloids, although not a life-threatening disease, can severely impair a patient's quality of life. Contact cryosurgery is a safe technique for the management of earlobe keloids with tolerable side effects. The aim of this study was to assess the safety and efficacy of contact cryosurgery in the treatment of earlobe keloids through a 1-year prospective study. We treated 15 Caucasian women ranging in age from 8 to 54 years with a total of 18 earlobe keloids. Excellent improvement was noted in 11 earlobe keloids, with a 75%-100% reduction in the volume of the keloids. An improvement ranging from 50% to 75% was observed in the seven other earlobe keloids. During the 18-month follow-up period, there was no evidence of bleeding, infection, recurrence, or permanent hypopigmentation. Two patients had a transient hypopigmentation which disappeared 2 months after the final session of contact cryosurgery. The results of our study highly encourage the use of contact cryosurgery which has tolerable side effects and high safety.

Abstract
The aim of this study was to estimate genetic parameters of milk urea concentration (MU) and its genetic correlations with milk production traits, longevity, and functional traits in the first 3 parities in dairy cows. The edited data set consisted in 9,107,349 MU test-day records from the first 3 parities of 560,739 cows in 2,356 herds collected during the years 1994 to 2020. To estimate the genetic parameters of MU, data of 109 randomly selected herds, with a total of 770,016 MU test-day records, were used. Genetic parameters and estimated breeding values were estimated using a multiple-trait (parity) random regression model. Herd-test-day, age-year-season of calving, and days in milk classes (every 5 d as a class) were used as fixed effects, whereas effects of herd-year of calving, permanent environment, and animal were modeled using random regressions and Legendre polynomials of order 2. The average daily heritability and repeatability of MU during days in milk 5 to 365 in the first 3 parities were 0.19, 0.22, 0.20, and 0.48, 0.48, 0.47, respectively. The mean genetic correlation estimated among MU in the first 3 parities ranged from 0.96 to 0.97. The average daily estimated breeding values for MU of the selected bulls (n = 1,900) ranged from -9.09 to 7.37 mg/dL. In the last 10 yr, the genetic trend of MU has gradually increased. The genetic correlation between MU and 11 traits of interest ranged from -0.28 (milk yield) to 0.28 (somatic cell score). The findings of this study can be used as the first step for development of a routine genetic evaluation for MU and its inclusion into the genetic selection program in the Walloon Region of Belgium.

Abstract
INTRODUCTION to describe the epidemiological, clinical, therapeutic and evolving characteristics of Behçet´s disease and identify prognostic factors. METHODS we have realized a retrospective, single-center study, conducted over a period of 26 years and including 130 patients presenting Behçet´s disease and hospitalized in an Internal Medicine Department. RESULTS the mean age of the Behçet´s disease at onset was 30.3 ±8.8 years and that at diagnosis was 34.6 ±9.4 years. The sex ratio (male/female) was 2.5. The mean delay of diagnosis was 53.5 months. Oral aphthosis was constant. The frequency of the manifestations was: genital aphtosis 71.5%, pseudofolliculitis 84.6%, erythema nodosum 11.5%, positive pathergy test 50%, ocular disease 36.9%, venous thrombosis 30%, arterial disease 4.6%, joint damage 30.8%, neurological disease 19.2% and digestive disease 0.8%. The male gender was significantly associated with ocular involvement (p =0.02), venous disease (p =0.01) and occurrence of relapses (p =0.01). The mean follow up was 68.5 ± 77.3 months. The poor survival prognostic factors were male gender, ocular involvement, venous disease, cardiovascular disease, a duration of follow up ≤12 months and a diagnostic delay ≤ 24 months. Conclusion: improving the prognosis of Behçet´s disease requires a shortening of the time to diagnosis, multidisciplinary collaboration, intensive treatment of functional threats, regular monitoring, and patient adherence.

Abstract
BACKGROUND Lichen planus (LP) is a chronic inflammatory dermatosis that affects the skin and the mucous membranes. The literature on the dermoscopic aspects of mucosal LP is still scarce. This study aimed to describe the dermoscopic aspects of mucosal LP and to provide a comprehensive updated summary of the literature. METHODS This was a cross-sectional, multicenter study conducted in Charles Nicolle, La Rabta, and Habib Thameur hospitals from December 2019 to October 2020. We included patients with histologically confirmed mucosal LP for whom a dermoscopic examination was performed. RESULTS Twenty-seven patients were enrolled. The main dermoscopic structures observed were as follows: Wickham's striae (WS) (91%), vessels (88%), pigmentated structures (41%), erosions (63%), scales (34%), and blunting of lingual papillae (3.1%). WS patterns were as follows: reticular (67%), radial (48%), annular (30%), globular (15%), dotted/starry sky (15%), and veil-like blue or grey-white homogenous pattern (19%). Vascular structures were as follows: linear (85%), dotted (70%), looped (22%), and peripheral sea anemone-like vessels (37%). These vessels were distributed in a radial arrangement at the periphery of the lesions in 67% of the cases. Pigmented structures included brown/blue globules (33%), grey-blue dots (30%), and brown dots (26%). CONCLUSION Dermoscopic features of mucosal LP are varied. WS is the hallmark of LP. The distribution and aspects of WS in mucosal LP were slightly different from those described in cutaneous LP. Physicians should be aware of these dermoscopic features that could help differentiate LP from other mucosal inflammatory diseases.
