Intradermal tranexamic acid microinjections: a novel treatment option for erythematotelangiectatic rosacea.

BACKGROUND: Treatment options for erythematotelangiectatic rosacea (ETR) are still scarce. Tranexamic acid (TXA) is an antifibrinolytic drug that was recently used for the treatment of ETR. AIMS: To evaluate the efficacy and safety of intradermal microinjections of TXA for ETR. PATIENTS/METHODS: This was a retrospective study enrolling patients, treated with TXA intradermal microinjections for ETR, from January 2019 to February 2020. Response to treatment was assessed based on subjective symptoms, clinical photographs, and the Investigator Global Assessment of Rosacea Severity Score (IGA-RSS). RESULTS: Six patients were included. The mean number of monthly intradermal TXA microinjections was 5.1 ± 1.3. The mean decrease of IGA-RSS was 2.4 ± 0.5. Local side effects, mainly transient erythema and swelling, were noticed in three cases. No systemic effects were noted. Clinical improvement, in respondent patients, lasted after 3 months of follow-up. CONCLUSION: Intradermal TXA microinjections are a safe and effective treatment option for ETR. The optimal number of monthly sessions has yet to be determined.

Dermoscopic features of lupus miliaris disseminatus faciei: Distinct aspects depending on disease stage.

Dermoscopy is a useful tool that helps distinguish lupus miliaris disseminatus faciei (LPDF) from sarcoidosis and tuberculosis. Follicular keratotic plugs (FKP) represent the hallmark of LPDF. Dermoscopic aspect of LPDF changes through the course of the disease.

Erosive lichen planus of the soles: Effective response to prednisone.

BACKGROUND: Erosive lichen planus (LP) of the soles is a rare variant of LP, characterized by chronic, painful, and disabling plantar ulcerations. Herein, we report a case with complete healing following treatment with systemic steroids. CASE REPORT: A 38-year-old woman was referred with painful and disabling erosive bilateral plantar LP, which she had experienced for 6 weeks. A 1 mg/kg/day, oral prednisone therapy led to rapid improvement and complete healing within 3 weeks, with a sustained result under a low dose maintenance therapy. DISCUSSION: Ulcerative plantar LP is significantly known to be unresponsive to several topical and systemic therapies. Surgical excision and grafting is the treatment of choice. Systemic steroids are reported to have inefficient or partial results; both on cutaneous healing and on maintenance of the result. Our patient achieved complete cicatrisation with a sustained result of 3 months under a low dose of prednisone (5 mg/day).

Nevus lipomatosus cutaneous superficialis: Report of eight cases.

INTRODUCTION: Nevus lipomatosus cutaneous superficialis (NLCS) is a rare benign hamartomatous skin tumor characterized by dermal deposition of mature adipose tissue. It's classified in two types: the classical form with multiple soft, pedunculated, cerebriform papules and nodules that coalesce into plaques, and the solitary form that consists of a solitary papule or nodule. In this study, eight cases of NLCS are reported. METHODS: The study was a retrospective case series including all patients with histopathologically documented NLCS who attended the Dermatology Department of Charles Nicolle hospital between January 1997 and December 2010. The objective of our study was to determine the epidemioclinical characteristics, the histopathologic features, and the treatment of this hamartoma. Patients included three males and five females aged between 7 and 41 years. RESULTS: In four cases hamartoma was present since childhood, and in the other four cases it appeared in the third and fourth decades. Classical form was noted in seven cases and the solitary form in one case. Lesions involved limbs in four patients and trunk in four patients. Seven patients underwent surgical excision, and for one case no treatment was proposed. CONCLUSION: The multiple or classical form is largely predominant in our study. Habitually, NLCS has an asymptomatic course. Treatment is usually not necessary unless for cosmetic reasons; surgical excision is curative and recurrence after is rare.

Bullous Darier's disease mimicking Hailey-Hailey disease.

BACKGROUND: The bullous variant of Darier's disease (DD) is a rare type characterized by histological and clinical overlap with Hailey-Hailey disease (HDD). CASE REPORTS: The following case report describes two cases of familial DD; a 51-year-old woman who presented with erythematous plaques, covered by small blisters in axillary and inguinal areas, and the first patient's daughter, who presented with keratotic papules localized on the axillary and inframammary folds. CONCLUSION: These two cases are original by the predominant flexural distribution, and by a bullous form in the first case, clinically and histologically mimicking HHD.

Lupoid cutaneous leishmaniasis: a case report.

BACKGROUND: Lupoid cutaneous leishmaniasis (CL) is a rare form of CL having a striking resemblance to other granulomatous cutaneous conditions of infectious or inflammatory origin. The authors present a patient with a facial lupoid CL and discuss the diagnostic tools of this parasitological infection, the main differential diagnosis, and treatment. CASE REPORT: A 54-year-old Tunisian woman, with no past medical history of lupus erythematosus or infectious disease, presented with a 3-month history of a slowly enlarging erythematous and infiltrated plaque, extending over the nose, the right cheek, and the internal aspect of the right lower eyelid. Microscopic examination of a parasitological smear showed numerous leishmania in their amastigote form, inside monocytes, confirming the diagnosis of CL. Clinical aspect was in favor of lupoid CL. The patient was cured by fluconazole 200 mg/day for 6 weeks after pancreatic intolerance with intramuscular meglumine antimoniate (60 mg/kg/day for 7 days), and no response to doxycycline (200 mg/day for 6 weeks). DISCUSSION: Lupoid CL is easily suspected in countries in which there is an endemic of leishmaniasis. In countries where there isn't an endemic, although rarely observed, this diagnosis should also be kept in mind in front of an infiltrated facial lesion of a tuberculoid aspect on histology, especially when there is a positive travel history to an area in which there is an endemic.

PUVA therapy and narrowband UVB therapy in Tunisian patients with mycosis fungoides.

BACKGROUND: PUVA therapy and narrowband UVB therapy (NBUVB) constitute a widely used first line therapy in mycosis fungoides (MF). METHODS: It is a retrospective study dealing with 7 patients with MF treated by phototherapy [3 with PUVA (III, IV, V phototype) and 4 with NBUVB (III-IV phototype)]. One patient had both treatments (PUVA then NBUVB for a relapse). RESULTS: Complete response (CR) was achieved in 2 of the 3 patients treated with PUVA (they had stage IB-MF). Both had relapsed after 40 sessions and 7 months later, respectively. Relapses were treated by PUVA maintenance treatment (2 sessions/2 weeks) and NBUVB leading to CR. The third patient (stage IIA) did not respond to PUVA. CR was obtained in the 5 patients treated with NBUVB (stage IA-IB), after a mean cumulative dose of 58.3 J/cm(2). No relapse was noted with NBUVB after a mean follow-up period of 13.2 months (extremes: 2 -31 months). CONCLUSION: NBUVB is only effective on non-infiltrated plaques independently of phototype. PUVA therapy is effective even on infiltrated plaques. Both treatments do not prevent relapses.

[Pustular psoriasis in childhood in 15 cases]. / Psoriasis pustuleux juvenile. A propos de 15 cas.

Psoriasis is a common, chronic and recurrent, inflammatory disease of the skin. Children were affected in 30% of cases. Severe form can be observed: pustular psoriasis (PP), psoriatic arthropathy and erythrodermic psoriasis. There were 15 children with PP, with an age range of 1-15.5 years, (mean age 7.56 years). Psoriasis constituted 5% of the total dermatological disorders in children. The severe forms of psoriasis were rare in children Annular PP was the most common form of PP in children. Juvenile PP had generally better prognostic than in adults, but the evolution is characterized by recurrences.

[Dermatofibrosarcoma in children. Report of 7 Tunisian cases]. / Dermatofibrosarcome de l'enfant. A propos d'une série tunisienne de 7 cas.

Dermatofibrosarcoma (DFS) protuberans is a rare mesenchyma tumor in childhood characterised by slow growth. We report the result of a retrospective study of 7 childhood (4 males) cases of through a fifteen year period. The mean age was 13 years. 4 Tumors were (DFS) located on the limbs: 2 on the trunk: and on the scalp. Clinical types were multinodular and infiltrated in 3 cases, nodular in two cases and ulcerated with budding also in two cases. The mean delay between diagnostic and the appearance of the tumor was about 24 months for 4 initial tumors. Histological features were typical in all cases. We report 3 recurrences of dermatofibrosarcoma arising few months after surgical excision of an initial tumor, in one case the tumor was diagnosed histocytofibroma. Six patient underwent surgical excision with wide margins, and in one case the margins were considered borderline. No recurrences were reported, the follow-up was between 17 months to 9 years. It's a rare tumor in childhood, 160 cases were reported. The clinical and evolutive mode were entirely comparable to the adult cases. However the initial appearance as benign atrophic or indurated plaque is more frequent in childhood, but this appearance wasn't noted in our series.

[Mycosis fungoides. Study of a series of 11 Tunisian cases]. / Le mycosis fongoïde. Etude d'une série Tunisienne de 11 cas.

Mycosis fungoides is an epidermotropic cutaneous T lymphoma. It's a non Hodgkinian lymphoma. We report the results of a retrospective review of 11 mycosis fungoide seen during 22 years. The frequency of MF was about 39.3% among all cutaneous lymphoma. Six patients were male and 5 were female; the mean age was about 56 years. Mean delay between diagnostic and the first manifestation was about 25 months. All patients had the progressive form: 4 had infiltrate plaques and 7 were at the tumoral phase. Lymph nodes and medullar metastases were noted respectively in 1 and 2 cases. Treatment was mono or polychemotherapy associated in 6 cases with topical drug. Three patients died of their diseases According to our experience and after reviewed the literature, we notice that our patients are slightly younger without male predominance. The diagnostic was done tardily and this may explain the pejorative prognostic.

[Wolfram syndrome. A new case report]. / Le syndrome de Wolfram. A propos d'une nouvelle observation.

The WOLFRAM syndrome (SW) is a rare hereditary disorder described for the first time in 1938 as the coexistence of a diabetes mellitus and an optic atrophy to which join frequently a diabetes insipidus and a bilateral deafness. Several genetic studies are current to determine transmission mechanisms, physiopathology of the disorder to update a curative therapy. On the occasion of a new case report we remind the main characteristics of this syndrome. The SW is a rare neurodegenerative disorder characterized by the coexistence of diabetes mellitus, diabetes insipidus, optic atrophy and deafness. Several other manifestations are frequently associated: neurological, urologic and endocrinous abnormalities as well as growth troubles. Only diabetes mellitus and optic atrophy are compulsory for the diagnosis. This Syndrome is transmitted to the autosomic recessive mode. Mitochondrial heredity is in the course of study. The systematic practice of a cerebral IRM during a SW allows finding several malformative abnormalities of which the most typical is the agenesis of the post-pituitary gland. The prognosis of the affection is essentially conditioned by the evoluting complications of the uropathy and the diabetes mellitus. The treatment is symptomatic. Genetic therapy is in.
