Primary Syphilis Presenting As a Chronic Lip Ulcer.

Syphilis is usually a sexually transmitted infection caused by the spirochete Treponema pallidum. Primary syphilis classically presents as a painless, ulcerated lesion on the genitals. However, the primary lesion is not restricted to this site and appears wherever the spirochete enters through the skin.

Utility of topical agents for radiation dermatitis and pain: a randomized clinical trial.

Purpose: Although topical agents are often provided during radiation therapy, there is limited consensus and evidence for their use prophylactically to prevent or reduce radiation dermatitis.

Methods: This was a multi-site, randomized, placebo-controlled, blinded study of 191 breast cancer patients to compare the prophylactic effectiveness of three topical agents (Curcumin, HPR Plus™, and Placebo) for reducing radiation dermatitis and associated pain. Patients applied the topical agent to their skin in the radiation area site three times daily starting the first day of radiation therapy (RT) until 1 week after RT completion.

Metastatic squamous cell carcinoma arising in the setting of folliculitis decalvans.

Squamous cell carcinomas (SCCs) often arise secondary to UV-induced DNA damage resulting in genetic mutations, but can also occur in the setting of prolonged inflammation. Folliculitis decalvans (FD) is a rare cicatricial alopecia with a complex, multifactorial pathogenesis that results in chronic inflammation and scarring. We present a patient with severe, chronic FD who developed metastatic squamous cell carcinoma of the scalp.

Intralymphatic histiocytosis treated with intralesional triamcinolone acetonide and pressure bandage.

Intralymphatic histiocytosis is a rare disorder associated with a variety of inflammatory conditions. We report the case of an 89-year-old woman with a history of a right knee replacement and a ruptured popliteal cyst who developed an erythematous indurated plaque over the surgical scar. Histopathology revealed fibrosis, chronic inflammation, and histiocytes within the lymphatics consistent with intralymphatic histiocytosis.

Trigeminal trophic syndrome with histopathologic correlation.

We present the case of a 49-year-old woman with trigeminal trophic syndrome (TTS), also known as trophic trigeminal neuralgia, trigeminal neurotrophic ulceration, and/or trigeminal neuropathy with nasal ulceration. Our case represents an uncommon report of intractable itching and chronic pain associated with TTS. Emphasis was placed on skin biopsy histology, which revealed no neuronal innervation of the affected scalp despite reports of intractable itching and chronic pain.
