Rosai-Dorfman Disease: Cutaneous and Parotid Involvement.

Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare and benign proliferative disease that affects histiocytes. Its etiology remains unclear. Rosai-Dorfman disease primarily affects lymph nodes with many extranodal manifestations present, including cutaneous, pulmonary, ophthalmic, and gastrointestinal. Diagnosis is mainly histologic with the presence of Rosai-Dorfman cells, which demonstrate emperipolesis. We report a case of a 30-year-old man who presented with a facial cutaneous mass and was diagnosed with RDD; he underwent surgical excision. The patient experienced recurrent lesions on the surgical scar and parotid gland as well as the lower back. Treatment consisted of systemic steroids and surgical excision.

The Complicated Facial War Injury: Pitfalls and Mismanagement.

OBJECTIVE: The aim of this paper is to share the authors' experience in the management of complicated facial war injuries using free tissue transfer. A discussion on the most commonly encountered pitfalls in management during the acute and complicated settings is presented in an effort to raise insight on facial war wound complications. METHODOLOGY: Two patients of complicated facial war injuries are presented to exemplify the pitfalls in acute and chronic management of the mandibular region in the first patient and the orbito-maxillary region in the second. The examples demonstrate free tissue transfer for early as well as late definitive reconstructions. RESULTS AND DISCUSSION: A reconstruction algorithm or consensus regarding the optimal management plan of complicated facial war injuries is not attainable. The main principles of treatment, however, remain to decrease bacterial burden by adequate aggressive debridement followed by revisit sessions, remove of all infected hardware followed by replacement with external bony fixation if necessary and reviving the affected area by coverage with well-vascularized tissues and bone. The later is feasible via local, regional, or distant tissue transfer depending on the extent of injury, surgeon's experience, and time and personnel available. CONCLUSION: Free tissue transfer has revolutionized the management of complicated facial war injuries associated with soft tissue or bone loss as it has allowed the introduction of well-vascularized tissues into a hostile wound environment. The end result is a reduced infection rate, faster recovery time, and better functional outcome compared with when loco-regional soft tissue coverage or bone grafting is used. When soft tissue or bone loss is present, free tissue transfer should be the first management plan if time and personnel are available. The ultimate treatment of a complicated war wound remains prevention by accurate initial management.

Refractory sickle cell leg ulcer: is heparan sulphate a new hope?

Patients with sickle cell disease are known to have recurrent lower extremity ulcers that have a high pain score and are resistant to conventional means of wound therapy. This study reports the successful use of synthetic heparan sulphate (Cacipliq20(®) , OTR3, Paris, France) in the treatment of a sickle cell ulcer that had failed to respond to several other means of treatment. Therapeutic success was assessed by complete wound coverage and vast improvement in pain score. This is the first study to report use of heparan sulphate in sickle cell ulcers.

Caso original de lipo-hipertrofia simétrica: relato de caso e revisão de literatura / An original case of symmetric lipohypertrophy: case report and review of the literature

Paciente do sexo feminino, saudável, meia-idade e com história prolongada de massas com crescimento lento localizadas bilateralmente e simetricamente nos membros superiores e inferiores, próximas às principais articulações. Exames de imagem e patológicos após excisão das massas revelaram massas constituídas por gordura subcutânea normal. Não houve evidências de lipomas bem-circunscritos. Na revisão de literatura, destacaram-se diversos distúrbios lipo-hipertróficos, com possível apresentação simétrica. As características das afecções encontradas não eram, porém, totalmente concordantes com as características de nossa paciente. Embora não de modo absoluto, a doença que mais estreitamente se assemelhou ao caso foi lipodistrofia simétrica rara, conhecida como doença de Madelung. Dos 150 casos relatados, em apenas 3 foi descrito comprometimento dos membros inferiores, como ocorreu em nosso caso. Este relato apresenta descrição detalhada do caso, seu manejo e seguimento no pós-operatório. Os tipos distintos de lipodistrofias simétricas também são discutidos.

A middle-aged healthy woman who presented with longstanding history of slow growing masses located bilaterally and symmetrically on the upper and lower extremities closed to major joints. Imaging and pathology tests following excision of masses revealed normal subcutaneous fat. There was no evidence of well-circumscribed lipomas. A review of the literature identified a number of lipohypertrophic disorders, which may be present in a symmetrical fashion. The characteristics of the disorders, however, did not fully agree with characteristics observed in our patient. Although not absolute, the closest disease found to fit our case is a rare symmetrical lipodystrophy known as Madelung's disease. Of 150 reported cases, only 3 described involvement of lower extremities as seen in our case. We report a detailed description of a case, its management and post-operative follow-up. Different types of symmetrical lipodytrophies are also discussed.
