Article Synopsis
  • Juvenile xanthogranuloma (JXG) is a rare, non-cancerous skin condition mainly affecting children, often resolving on its own without treatment.
  • In some cases, like the one discussed in the paper, JXG can appear as a single lesion that may require surgical removal if it causes functional issues.
  • The case highlighted involves a child whose JXG lesion on the sole led to delays in walking and bearing weight, prompting the need for surgery.

The explosion of headphones is a rare incident, not reported in the literature, and is responsible for serious burns involving functional and aesthetic consequences with a major psychological impact. We report here the case of a young boy in order to raise awareness in the population and draw attention to these risks.

A 17-year-old male with chest malformation and left breast enlargement underwent surgery for gynecomastia. Histological examination revealed mammary fibrous stroma with ductal hyperplasia and features of pseudoangiomatous stromal hyperplasia. Postoperative follow-up showed no complications, but 8 months later, the patient experienced a mild recurrence with enlargement of the nipple-areolar complex.

Pyogenic granuloma (PG) is a benign vascular proliferative tumor of the skin and mucous membranes, it can appear spontaneously or following triggering factors. Different clinical aspects are described, pyogenic granulomas following burns (GB) are rare. We report a case of post-burn pyogenic granuloma confirmed by histological study and treated surgically.

  • Biobanks, like the BRO Biobank established in Morocco in 2015, are essential for storing human biological specimens along with personal and clinical data to aid medical research, particularly involving underrepresented ethnic groups.
  • The BRO Biobank has recruited 2,446 participants over 5 years, with a significant number being healthy donors and patients, including many with rare diseases and other serious conditions.
  • High-quality biospecimens (5,092 collected) have been gathered, ensuring they can be used effectively for various biomedical studies due to rigorous standard operating procedures.

 Giant cell tumor (GCT) of bone is rare in the carpus, and only 11 cases have been reported in the capitate bone. The problem with this location is the high recurrence rate due to easy extension to the adjacent joint spaces and bones. We describe a case of GCT on the capitate bone and the treatment in comparison with the previously reported cases.

Introduction: Dermatofibrosarcoma protuberans (Darrier-Ferrand sarcoma, DFSP) is an uncommon tumor. This sarcoma has a tendency to local recurrence, requiring a wide surgical resection.

Observation: We report herein two cases of patients presenting with recurrent dermatofibrosarcoma protuberans after several surgical resections.

Purpose: To study the epidemiologic, clinical and histological aspects of eyelid carcinomas in our context, and to evaluate our surgical management on an oncological, functional and aesthetic level.

Patients And Methods: This work is a retrospective bicentric study extended over a 5-year period between January 2009 and December 2013, including 64 patients with eyelid carcinoma undergoing surgery in the Plastic and Reconstructive Surgery Department at the Avicenne University Hospital of Rabat and in the ENT/Head and Neck Surgery Department at the Hassan II University Hospital of Fez.

Results: The study included 25 men and 39 women with a mean age of 60.

Six sequenced and annotated genomes of Paenibacillus larvae phages isolated from the combs of American foulbrood-diseased beehives are 37 to 45 kbp and have approximately 42% G+C content and 60 to 74 protein-coding genes. Phage Lily is most divergent from Diva, Rani, Redbud, Shelly, and Sitara.

The superomedial thigh flap is a reliable and easy method for scrotal reconstruction described in 1980 and infrequently reported in the literature since its description. We used it for four patients presenting scrotal defects after Fournier's gangrene with some technical modifications to improve the esthetic results and to facilitate the closure of the donor area. We describe the technical steps and the results.

Desmoid tumors most often occur in abdominal wall. Their tendency to recur lead to repeated operations which can make the abdominal wall reconstruction difficult. We report a 28-year-old female history.

The hand - the major organ of grip - can suffer consequences from severe burns that compromise its normal functioning. Although the hand counts for only 2% of the body surface, hand burns are serious and difficult to manage, in view of the vulnerability and complexity of its musculoskeletal system. We report the case of a patient who suffered carbonization of the hand.

Diabetic neuropathy is a frequent complication of diabetes. The most frequent clinical form is known as "sock polyneuritis", with loss of sensitivity to pain in the feet. Hot water bottle burns are the prerogative of diabetic patients suffering from a form of sensitive polyneuropathy.

Background And Purposes: When the skin's laxity is limited, the preauricular cutaneous defect resulting from the Mustardé cheek rotation flap for the coverage of suborbital skin defects is very difficult to close even with a large undermining of the cervicofacial skin. The rotation of the temporoparietal scalp in an opposite direction compared to the Mustardé flap or the 'Yin-Yang' rotation of these flaps is interesting for two reasons: it allows an easy closure of this preauricular defect with a limited facial undermining and it suspends with efficiency the Mustardé flap at the temporal area avoiding the lower lid's ectropion.

Material And Methods: From September 2001 to April 2005, nine patients aged between 35 and 78 years old, with no facial skin laxity, have benefited from this technique to cover suborbital defects secondary to excision of basal cell carcinomas with a mean diameter of 6 cm.

Subject: The advanced tumors of the scalp can involve the calvarium, the dura and the cerebral tissue. The medium sized full thickness scalp defects secondary to the excision of such cutaneous malignancy can be successfully treated with local flaps coming from the remaining scalp if these flaps are large and including at least one major pedicle of the scalp. The cranioplasty can be done immediately or secondarily.

Purpose: The distally based fasciocutaneous flaps of the leg are very useful for the treatment of skin defects at the lower third of the leg and the foot, but the venous congestion due to the reverse flow can be responsible of necrosis at the distal part of the flap. The anastomosis of the lesser saphenous vein which is included in the flap's dissection to the greater saphenous vein near the defect avoid this venous congestion and the necrosis of the most useful part of the flap for the coverage of these defects.

Material And Methods: From January 1999 to June 2005, 15 patients aged between 22 and 64 years old have benefited for the treatment of soft tissue defects secondary to trauma with a mean diameter of 7 x 10 cm and located in 7 cases at the lower third of the leg and in 8 cases at the posterior side of the heel, from distally based posterior fasciocutaneous flaps where the venous reverse flow has been changed in a physiological one by the terminolateral anastomosis between the lesser and greater saphenous vein.
