Lower Extremity Nodules After Spelunking in Mexico.

Mycobacterium marinum is a non-tuberculous mycobacterium that presents as a nodular granulomatous disease. The bacillus can infect humans when broken skin is exposed to a contaminated aquatic environment. M. marinum infections are usually isolated to the skin and soft tissues and can spread in a lymphatic distribution. A 26-year-old male cut his right ankle while spelunking in Tulum, Mexico. He presented to his primary care physician three months after he sustained the laceration with a nonhealing wound on the right lateral posterior ankle. Examination of the lesion demonstrated erythematous, violaceous, and hyperpigmented indurated plaques with satellite lesions noted at the right medial, posterior, and lateral ankle. The lesion characteristics raised initial suspicion for an invasive fungal infection. Biopsy of the lesion demonstrated epidermal ulceration covered by neutrophilic serum, marked underlying dermal acute inflammation, and granulation tissue. A mild perivascular, predominantly lymphocytic infiltrate was present in the deep dermis with no evidence of granuloma. Acid-fast bacilli culture plated onto chocolate agar confirmed the species M. marinum.

This case report describes hyperpigmented, indurated, and sclerotic plaques on the anterior trunk and upper abdomen with overlying scale that were studded with firm, erythematous papules.

Postoperative Candida Infection following Complex Periocular Reconstruction.

Postoperative candida infection is a rarely reported complication in cutaneous surgery, although it may develop more often in particular clinical settings. We present a 59-year-old woman with a well-controlled human immunodeficiency virus infection. She developed a bright red eruption with satellite pustules 2 weeks after excision of recurrent lentigo maligna melanoma of the left lower eyelid and periocular region. Due to defect size and complexity of the reconstruction (glabellar transposition flap, Hughes flap, composite graft from upper contralateral eyelid, and full-thickness skin graft from ipsilateral retroauricular region), she was placed on prophylactic oral amoxicillin-clavulanic acid and topical bacitracin and polymyxin. Immediate postoperative course was unremarkable, and sutures were removed after 7 days. Three days later, she developed bright red erythema and pustules within the surgical site and complained of burning. Empirically she was switched to topical gentamicin and oral ciprofloxacin, and later to linezolid, due to inadequate response. Wound culture grew Candida albicans sensitive to fluconazole and voriconazole. After oral fluconazole and topical clotrimazole initiation, the patient rapidly improved. The graft remained viable and apart from small partial dehiscence on the cheek, the healing was unremarkable. Apart from the case presentation, we also discuss different factors associated with postoperative candida infection, including immunocompromised status, surgical procedure location, and postoperative antibiotic use. Early recognition and treatment of postoperative candida infections are crucial to prevent delayed healing and associated morbidity.

The Sign of Leser-Trelát and Malignant Acanthosis Nigricans Associated With Fallopian Tube Carcinoma.

BACKGROUND: The sign of Leser-Trelát is controversial and rarely reported in gynecologic malignancies. It is characterized by rapid development of new or enlarging seborrheic keratoses. CASE: A 78-year-old woman presented with unintentional weight loss and new-onset erythematous patches and plaques with thickened, rugated skin and stuck-on brown waxy papules on the chest and back. Her symptoms were concerning for a paraneoplastic eruption; workup revealed an elevated CA 125 level and an ovarian mass on abdominal computed tomography scan. Exploratory laparotomy revealed a stage IIIC serous fallopian tube carcinoma and a synchronous low-grade endometrioid adenocarcinoma of the endometrium. CONCLUSION: The sign of Leser-Trelát can be associated with fallopian tube carcinoma. When recognized, paraneoplastic dermatoses can prompt clinicians to initiate a workup for occult malignancy.

The patient was first diagnosed with candida vaginitis, but a second opinion and a closer look at the clinical picture gave way to a different diagnosis.
