Facial pyoderma gangrenosum in senescence

Progressive Facial Ulcer: A Case Report of Pyoderma gangrenosum

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis characterized by rapidly developing and painful skin ulcers with distinctive features. As far as we are concerned, there is no previous case report on facial PG in East-Asia. In this case, we describe a case of a 79-year-old man with a 3-month history of progressive painful ulcers on his cheek and upper lip. Initial suspicion of atypical mycobacterium infection led to an ineffective treatment regimen. Comprehensive infectious testing yielded negative results, and a positive pathergy test indicated a potential diagnosis of PG. A skin biopsy confirmed the diagnosis, and the patient showed significant improvement with intravenous methylprednisolone and oral cyclosporine treatment. After three months, complete resolution of the lesions was achieved without recurrence. The case highlights the diagnostic challenges associated with PG, which is often misdiagnosed due to its resemblance to other conditions. Thorough evaluation is crucial to exclude alternative diagnoses, particularly cutaneous infections. Clinical morphology, tissue biopsy, and culture are essential for accurate diagnosis. The presence of pathergy, the development of new lesions following minor trauma, can also be a diagnostic clue.

Vaginal cuff pyoderma gangrenosum with associated ureteral stricture: A case report

Pyoderma gangrenosum is a sterile inflammatory disease of unknown etiology characterized by recurrent cutaneous ulcers. It can occur in extracutaneous locations, especially at operative sites, and has been reported following gynecologic surgery. This report is the first case of pyoderma gangrenosum as a remote complication of pelvic surgery with associated ureteral stricture. It demonstrates the diagnostic challenge of this rare disease and the importance of broadening the differential diagnosis when apparent infections do not respond to treatment to minimize the morbidity of ineffective antibiotic and surgical interventions.

Multiple Facial Lesions of Recalcitrant Pyoderma Gangrenosum Successfully Treated with Adalimumab

Pyoderma gangrenosum (PG) is a rare, ulcerative, inflammatory skin disease that most commonly presents on the lower legs. Development of PG on the head and neck is exceedingly rare. We present the case of a 52-year-old man with no known history of underlying systemic disease who developed multiple facial lesions of PG that were refractory to both standard and alternative treatment modalities. Clearance of disease was ultimately achieved using adalimumab.

Trigeminal trophic syndrome: an updated review

Trigeminal trophic syndrome (TTS) is a rare disease process that is thought to occur after insult to the trigeminal nerve. The earliest descriptions of this condition were provided in the early 20th century, yet it remains relatively unknown, with approximately 200 cases since described. Most commonly seen in older women, TTS characteristically involves persistent facial ulceration with loss of sensation and paresthesia along the distribution of the trigeminal dermatome. Ulceration often occurs in the alar region, following self-manipulation in response to paresthesias. Time of onset of TTS after trigeminal insult may vary from weeks to decades, and emergence of ulceration may be associated with psychiatric disorders. Diagnosis is clinical and made by exclusion of similarly presenting conditions. Histology is nonspecific yet necessary to exclude other causes of facial ulceration. Although there is not yet a standard management strategy, a number of successful approaches have been reported including pharmaceutical and surgical interventions, installation of a protector, and transcutaneous nerve stimulation. However, because of the self-inflicted manifestations of this disorder, behavioral modifications remain of the utmost importance. This review serves to address the history, epidemiology, pathogenesis, clinical presentation, histology, diagnosis, differential diagnosis, and management options for TTS.

Management of Facial Pyoderma Gangrenosum Using Platelet-Rich Fibrin: A Technical Report

This report describes a case of local pyoderma gangrenosum that was treated with short-term immunosuppressive therapy and the topical application of platelet-rich fibrin (PRF). Medical treatment included oral corticosteroid therapy and topical treatment with PRF in solid and liquid form. This therapy initially led to the reduction of the ulcer's size and an improvement in symptoms, until the ulcer was completely healed after a few weeks. A relapse was treated with only the application of PRF to the affected tissue with excellent recovery. The efficacy of PRF as a guide for wound healing is a result of the continuous release of growth factors involved in tissue repair mechanisms. PRF has proved to be suitable for the management of facial pyoderma gangrenosum while allowing a reduction in systemic corticosteroid therapy. The ease of preparation, low cost, and outpatient use make PRF an optimal scaffold for tissue healing processes.

Ocular pyoderma gangrenosum: A systematic review

BACKGROUND

Pyoderma gangrenosum (PG) is a rare, ulcerative cutaneous disorder. Ophthalmic involvement in PG is atypical, but can have devastating consequences.

OBJECTIVE

We sought to characterize ocular PG to allow for earlier diagnosis and therapy. To our knowledge, this is the first systematic review summarizing this clinical variant.

METHODS

A systematic review was conducted using PubMed and Web of Science. Data were extracted and studies were qualitatively assessed and analyzed.

RESULTS

We identified all 34 cases of PG involving the eye and periorbital area, and categorized them into 4 different subtypes. Common presenting signs include ulceration, peripheral ulcerative keratitis, and decreased visual acuity. Although it is often difficult to biopsy ocular PG, histologic features are nonspecific. Combined therapy using corticosteroids and further surgical reconstruction as needed is the mainstay of treatment. Cases of the eye/orbit in particular should be treated aggressively, as these are more likely to relapse compared with cases of the periorbital area.

LIMITATIONS

Use of case reports, paucity of ocular PG cases, and heterogeneity of studies are limitations.

CONCLUSION

PG should be considered in the differential diagnosis of ulceration of ocular/periocular tissues. An aggressive, early, multimodal treatment strategy should be used to prevent relapse, especially in cases of the eye/orbit.
