Typically, sporotrichosis follows an environmental transmission route via traumatic inoculation of contaminated plant or soil matter. Although familial occurrences of sporotrichosis are rare, human-to-human transmission is even rarer. Herein, we report two cases, a father and son, with sporotrichosis caused by Sporothrix (S.) globosa. A 33-year-old male who otherwise appeared healthy presented with a tender, erythematous, ulcerative crusted plaque on the left ala nasi and upper lip. A skin biopsy and mycological study revealed fixed cutaneous sporotrichosis. The patient irregularly received oral itraconazole with a relapsing course. Approximately a year later, his 3-year-old son developed a single plaque on the left leg. When the father carried his son on his shoulder, there was direct contact between the two lesions. Fungal culture results from the father and son's lesions confirmed S. globosa with ribosomal DNA ITS sequencing. In both patients, oral terbinafine exhibited better results than oral itraconazole. These cases are an excellent example of human-to-human transmission of sporotrichosis.
ABSTRACT
Fibrous hamartoma of infancy (FHI) is a rare entity with a benign nature. The typical clinical features are a single, slowly growing, painless mass on the trunk that appears within the first 2 years of life. We report a 13-month-old boy who presented with a plaque on the lower back since 4 months of age. The plaque had gradually become larger and firm, and hyperhidrosis and hypertrichosis were noticed. No visible connection between the spinal cord and the lesion was found in radiologic studies, indicating a disease other than spinal dysraphism. Histopathological findings showed well-defined fibrous trabeculae, mature adipose tissue, and primitive mesenchymal cells, all consistent with FHI. This is the first case of FHI presenting with hyperhidrosis and hypertrichosis reported in Korea.

A 46-year-old male presented with skin lesion on the tip of penis, occurring a month ago. Erythematous macules and grouped vesicles on the glans penis and upper side of prepuce area were noticed. In addition, scales were noticed on the tip of glans penis. The lesion was first diagnosed as herpes genitalis based on the clinical manifestation, but had failed to improve with systemic and topical antiviral and topical antibiotics. KOH examinations were performed on his upper glans penis, and we detected pseudo hyphae and spores. Fungal culture and polymerase chain reaction (PCR) study were revealed as Candida albicans. He was successfully treated with topical isoconazole cream twice a day. Candida balanitis refers to candida infections of glans penis. Infectious balanitis presented various clinical presentations, it is not easy to diagnose with clinical presentation only. Therefore, it is essential to include other examination such as KOH examination, microorganism exam, and/or biopsy in the differential diagnosis when cutaneous lesions are noticed in patients. Herein, we present a candida balanitis with atypical features that clinically mimicked herpes genitalis.

Primary cutaneous anaplastic large cell lymphoma (PCALCL) is a rare primary cutaneous lymphoma that is predominantly composed of large lymphoid cells that express the CD30 antigen. The skin lesion of PCALCL is usually single, ulcerative, and located on the trunk or extremities and rarely the palm. A 25-year-old woman presented with a plaque on the left palm for 20 days. The plaque was walnut-sized and purple to gray colored with erosion in the center. Histopathologic examination showed infiltration of large atypical cells in the dermis. The large tumor cells showed positivity for CD3, CD4, and CD30 and negativity for CD8, CD20, epithelial membrane antigen, and anaplastic lymphoma kinase. PET-CT showed no other hypermetabolic lesion except that on the left palm, and we finally arrived at a diagnosis of PCALCL. The patient was treated with an intralesional injection of methotrexate (25 mg/mL, 0.45 cc). After 3 months of treatment, the walnut-sized plaque had disappeared and a peripheral hyperpigmented patch remained.

Sporotrichosis is a chronic cutaneous fungal infection caused by Sporothrix (S.) schenckii complex. Fixed cutaneous sporotrichosis is one of the three subtype of sprotrichosis and accounts for 20% of total sporotrichosis cases. However, the incidence of total sporotrichosis cases is decreasing recently due to improvement of personal hygiene and industrialization. A 60-year-old woman presented to the hospital with multiple erythematous papules and ulcers on left cheek for 5 months. Histopathologic examination revealed chronic granulomatous inflammation and immunohistochemical staining was positive for GMS and PAS stain. The fungal culture on Sabouraud dextrose agar showed grayish dark brown colonies and the sequences of ribosomal DNA internal transcribed spacer region of clinical sample was 100% similarity with S. globosa. The patient was treated with oral itraconazole 200 mg daily and topical ketoconazole cream for 3 months. At that time after this treatment, skin lesion was almost cured and recurrence is not observed to date.
