Cutaneous Metastases: Clinicopathologic Study of 30 Patients.

Cutaneous metastases (CMs) of internal malignancies are uncommon. The breast in women and the lung in men represent the two elective sites of internal malignancies metastasizing to the skin. The aim of this study was to determine the epidemiologic, clinical, and pathologic features of CMs. A retrospective study of the patients diagnosed with CMs over 30 years was conducted. Thirty cases of CMs were enrolled in our study. In 16 cases (53%), the skin metastasis revealed the internal malignancy. The mean age was 66.4 years with sex ratio men/women of 2. CMs were solitary in 18 cases and multiple in 14 cases. The most frequent location was the chest (12 cases), followed by the abdomen (eight cases), the scalp (seven cases), and the arms (six cases). The common sites of primary malignancy were the lungs in men (nine cases) and the breast in women (three cases). Nine out of 30 patients died with an average of 33 months after diagnosis. In our study, the most frequent primary malignancy in men was lung cancer and in women breast cancer. The onset of CMs during the course of internal malignancy worsens the prognosis of the disease.

Idiopathic Granulomatous Mastitis Associated with Erythema Nodosum in a Pregnant Woman.

A 32-year-old woman at 17 weeks' gestation presented with fever and a 1-week history of an acute nodular eruption involving her legs, along with bilateral ankle and knee pain. She also had had a recurrent right breast abscess for 2 months for which she had been treated with oral antibiotics and surgical drainage, but with slight improvement. Cultures of the abscess showed no bacteria or fungi. She had no history of tuberculosis, sarcoidosis, trauma to the breast, or a family history of breast pathology. Cutaneous examination revealed multiple, tender, erythematous, subcutaneous nodules on her legs (Figure 1) and an ill-defined tender mass involving the inferior quadrant of the right breast without nipple discharge or retraction. There was a scar with drainage on her right breast (Figure 2). There were no regional lymphadenopathies. Left breast and left axilla examination was unremarkable. Significant laboratory findings included an erythrocyte sedimentation rate of 54 mm/hour (normal levels [NL] < 20 mm/hour), an elevated C reactive protein at 148 mg/L (NL < 5 mg/L), and a high level of white blood cells averaging 15,000 elements/mm3 (NL < 10,000/mm3).

Familial homozygous hypercholesterolemia with arcus cornea and xanthomas: A rare but serious entity.

Familial hypercholesterolemia (FH) is a rare but life-threatening disorder. Skin manifestations can be its only manifestation. We present a case of a fifteen-year-old female child, with multiple eruptive xanthomas, xanthomas anarcus, and a deranged lipid profile consistent with FH. The presence of this manifestation especially in the younger age group should draw attention to hypercholesterolemia. A timely diagnosis is fundamental to prevent serious complications and for early treatment.

Verrucous Carcinoma Arising in an Extended Giant Condyloma Acuminatum.

A 43-year-old heterosexual Tunisian man presented to the dermatology department with complaints of a genital friable mass. He had a past medical history of chronic hepatitis B. He was married and had a history of multiple sexual partners. The lesion had been present for over 10 years and gradually increased in size, disfiguring his genitalia. It had a major impact on his quality of life, preventing sexual intercourse and resulting in poor personal hygiene. On physical examination, the vegetative lesion presented as a giant cauliflower-like tumor (Figure 1) with a foul smell. The tumor involved the left inguinal region, the suprapubic genitalia, and was encircling the entire penile shaft. He also had inguinal lymphadenopathies. Under local anesthesia, a skin biopsy of the vegetative tumor was performed and sent for histopathologic examination. It revealed an exophytic epithelial tumor with papillomatosis, marked acanthosis, and many koilocytes, especially in the superficial layers of the epidermis. These signs along with the preservation of regular cytology were consistent with the diagnosis of condyloma acuminatum (Figure 2a). The histologic examination also showed clusters of atypical keratinocytes with high mitotic activity and keratinization, suggesting nests of squamous cell carcinoma (SCC) (Figure 2b and 2c). DNA-polymerase chain reaction (PCR) marker for Human papilloma virus (HPV) stains 11 was positive. Serology for hepatitis C, HIV, and syphilis non-reactive. Computed tomography scan of the abdomen and pelvis showed inguinal lymphadenopathies. The patient was referred to the oncologist for radiotherapy to reduce the size of the tumor followed by surgery.

Exceptional outcome in cutaneous myeloid sarcoma.

Recognition of cutaneous myeloid sarcoma is important for all dermatologists to avoid further progression to acute myeloid leukemia. Nevertheless, we highlight the presence of a favorable clinical outcome in some patients with spontaneous regression.

Solitary pigmented nodule on the trunk: What is your diagnosis?

The aim of my clinical image is to recall this rare and benign tumor and to emphasize the role of dermoscopy in the diagnosis.

Efficacy and Safety of Contact Cryosurgery in the Treatment of Earlobe Keloids.

Earlobe keloids, although not a life-threatening disease, can severely impair a patient's quality of life. Contact cryosurgery is a safe technique for the management of earlobe keloids with tolerable side effects. The aim of this study was to assess the safety and efficacy of contact cryosurgery in the treatment of earlobe keloids through a 1-year prospective study. We treated 15 Caucasian women ranging in age from 8 to 54 years with a total of 18 earlobe keloids. Excellent improvement was noted in 11 earlobe keloids, with a 75%-100% reduction in the volume of the keloids. An improvement ranging from 50% to 75% was observed in the seven other earlobe keloids. During the 18-month follow-up period, there was no evidence of bleeding, infection, recurrence, or permanent hypopigmentation. Two patients had a transient hypopigmentation which disappeared 2 months after the final session of contact cryosurgery. The results of our study highly encourage the use of contact cryosurgery which has tolerable side effects and high safety.

Primary and isolated cutaneous precursor B-lymphoblastic lymphoma in an infant.

Cutaneous lesions may represent the initial sign of various neoplasms in children, including histiocytosis, neuroblastomas, and lymphomas. Primary cutaneous lymphoblastic lymphomas are rare and involve mostly the B-cell phenotype. Herein, we report a case of isolated, primary B-lymphoblastic lymphoma in a 7-month-old infant and emphasize the importance of early diagnosis.
