Noninfectious Penile Lesions - Article
ABSTRACT: Family physicians commonly diagnose and manage penile cutaneous lesions. Noninfectious lesions may be classified as inflammatory and papulosquamous (e.g., psoriasis, lichen sclerosus, angiokeratomas, lichen nitidus, lichen planus), or as neoplastic (e.g., carcinoma in situ, invasive squamous cell carcinoma). The clinical presentation and appearance of the lesions guide the diagnosis. Psoriasis presents as red or salmon-colored plaques with overlying scales, often with systemic lesions. Lichen sclerosus presents as a phimotic, hypopigmented prepuce or glans penis with a cellophane-like texture. Angiokeratomas are typically asymptomatic, well-circumscribed, red or blue papules, whereas lichen nitidus usually produces asymptomatic pinhead-sized, hypopigmented papules. The lesions of lichen planus are pruritic, violaceous, polygonal papules that are typically systemic. Carcinoma in situ should be suspected if the patient has velvety red or keratotic plaques of the glans penis or prepuce, whereas invasive squamous cell carcinoma presents as a painless lump, ulcer, or fungating irregular mass. Some benign lesions, such as psoriasis and lichen planus, can mimic carcinoma in situ or squamous cell carcinoma. Biopsy is indicated if the diagnosis is in doubt or neoplasm cannot be excluded. The management of benign penile lesions usually involves observation or topical corticosteroids; however, neoplastic lesions generally require surgery.

ABSTRACT: Malignant lesions of the skin are common. Patients who develop squamous cell carcinoma and malignant melanoma often have recognizable precursor conditions. A few skin lesions resemble malignancies. Lesions that are growing, spreading or pigmented, or those that occur on exposed areas of skin are of particular concern. Knowing the similarities and differences between these lesions allows the primary physician to make a diagnosis in most cases by simple inspection and palpation. When in doubt, it is appropriate to perform an excisional biopsy of small lesions or punch biopsy of larger lesions. Removal of premalignant lesions will reduce the occurrence of malignant disease. Almost all skin cancers can be cured by early excision or destruction. For these reasons, physicians should be aware of the risk factors for skin cancer, educate patients about risk reduction and include skin inspection for premalignant and malignant lesions as a part of routine health maintenance examinations.
ABSTRACT: Vulvodynia is a problem most family physicians can expect to encounter. It is a syndrome of unexplained vulvar pain, frequently accompanied by physical disabilities, limitation of daily activities, sexual dysfunction and psychologic distress. The patient's vulvar pain usually has an acute onset and, in most cases, becomes a chronic problem lasting months to years. The pain is often described as burning or stinging, or a feeling of rawness or irritation. Vulvodynia may have multiple causes, with several subsets, including cyclic vulvovaginitis, vulvar vestibulitis syndrome, essential (dysesthetic) vulvodynia and vulvar dermatoses. Evaluation should include a thorough history and physical examination as well as cultures for bacteria and fungus, KOH microscopic examination and biopsy of any suspicious areas. Proper treatment mandates that the correct type of vulvodynia be identified. Depending on the specific diagnosis, treatment may include fluconazole, calcium citrate, tricyclic antidepressants, topical corticosteroids, physical therapy with biofeedback, surgery or laser therapy. Since vulvodynia is often a chronic condition, regular medical follow-up and referral to a support group are helpful for most patients.
ABSTRACT: Cutaneous T-cell lymphoma, also known as mycosis fungoides, is a malignancy of the T helper (CD4+) cells. Diagnosis is difficult early in the course of this disease because it mimics several benign skin disorders, including eczema, psoriasis and contact dermatitis. Cutaneous T-cell lymphoma is also difficult to identify histologically, and multiple biopsies may be necessary to confirm the diagnosis. Treatment may require a combination of topical and systemic agents. Patients with limited skin disease have a good prognosis, but the prognosis is less hopeful in those with extracutaneous involvement. As the disease progresses, the normal T-cell population is eliminated, and the patient becomes significantly immunosuppressed. Infection is the primary cause of mortality in patients with cutaneous T-cell lymphoma.
