BACKGROUND Hidradenitis suppurativa is a progressive, recurrent inflammatory disease. Surgical management is potentially curative with limited efficacy data. OBJECTIVE To evaluate hidradenitis surgical patients. METHODS Retrospective review of outcomes of 590 consecutive surgically treated patients. RESULTS Most patients were white (91.0% [435/478]), men (337 [57.1%]), smokers (57.7% [297/515]) with Hurley Stage III disease (476 [80.7%]). Procedure types were excision (405 [68.6%]), unroofing (168 [28.5%]), and drainage (17 [2.9%]) treating disease of perianal/perineum (294 [49.8%]), axilla (124 [21.0%]), gluteal cleft (76 [12.9%]), inframammary (12 [2.0%]), and multiple surgical sites (84 [14.2%]). Postoperative complications occurred in 15 patients (2.5%) and one-fourth (144 [24.4%]) suffered postoperative recurrence, which necessitated reoperation in one-tenth (69 [11.7%]) of patients. Recurrence risk was increased by younger age (hazard ratio [HR], 0.8; 95% confidence interval [CI], 0.7–0.9), multiple surgical sites (HR, 1.6; 95% CI, 1.1–2.5), and drainage-type procedures (HR, 3.5; 95% CI, 1.2–10.7). Operative location, disease severity, gender, and operative extent did not influence recurrence rate. CONCLUSION Excision and unroofing procedures were effective treatments with infrequent complications and low recurrence rates. Well-planned surgical treatment aiming to remove or unroof the area of intractable hidradenitis suppurativa was highly effective in the management of this challenging disease.

AbstractBackgroundHailey–Hailey disease (HHD) is an autosomal dominant genodermatosis that leads to skin breakdown and blister formation, usually in intertriginous areas. Laser ablation is a known surgical treatment for HHD.ObjectivesWe report outcomes in a series of patients with HHD treated with carbon dioxide (CO2) laser ablation.MethodsA retrospective chart review of data for 13 patients who underwent CO2 laser ablation for HHD was conducted. Questionnaires assessing effectiveness, pain, healing time, recurrence, new disease, complications, additional ablation, improvement in quality of life (QoL), and overall satisfaction were completed by all patients.ResultsAll patients had been recalcitrant to previous treatments prior to CO2 laser ablation. Anatomic sites treated and anesthesia techniques for the procedure varied. The mean ± standard deviation (SD) score for the effectiveness of CO2 laser ablation for HHD was 9.3 ± 0.9 (maximum: 10). All patients reported improved QoL. No patient had recurring disease within the treatment field. Five patients underwent additional CO2 laser treatments at new sites. One patient reported postoperative infection. No other complications were identified. The mean ± SD score for overall satisfaction with CO2 laser ablation was 8.9 ± 1.1.ConclusionsTreatment with CO2 laser ablation is very effective and can lead to prolonged or permanent remission in most HHD patients. Patients are highly satisfied with the results and report a substantial improvement in QoL.

Frozen section pathology is routinely used for margin assessment of non‐melanoma skin cancer ( NMSC ). Frozen section can also be used for the primary diagnosis of several skin lesions. Limited data exist on the accuracy of frozen section in the diagnosis of NMSC . We performed a retrospective chart review of 300 cases in which frozen section diagnoses were compared with permanent section diagnoses of NMSC . Frozen section and permanent section pathology were concordant 83.3% of the time, with the highest concordance rates noted for basal cell carcinoma (145/153, 95%). Our results show a high level of concordance between frozen section and corresponding permanent section pathology diagnosis for NMSC . The rapidity of frozen section tissue processing and pathology reporting makes this technique useful in dermatologic practice for immediate diagnosis and management of NMSC . Further studies should explore strategies to decrease or eliminate discrepancies between frozen and permanent section diagnosis.

AbstractBackgroundPatients with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), or non‐Hodgkin lymphoma (NHL) are at increased risk for the development of skin malignancies.ObjectivesThis study was conducted to estimate the incidences of rare skin malignancies in patients with CLL/SLL or NHL.MethodsPatients with a diagnosis of CLL/SLL or NHL recorded in the Surveillance, Epidemiology and End Results (SEER) database during 1992–2007 were identified. Diagnoses of specific skin malignancies were identified from SEER files.ResultsDuring 1992–2007, a total of 128,674 patients with first diagnoses of CLL/SLL or NHL were recorded in SEER; 4743 were excluded because follow‐up data were unavailable. Among the remaining 123,931 patients, 28,964 had CLL/SLL and 94,967 had NHL. Standardized incidence ratios (SIRs) for invasive malignant melanoma, Merkel cell carcinoma, malignant fibrous histiocytoma, dermatofibrosarcoma protuberans, Kaposi's sarcoma, and sebaceous carcinoma were 2.3, 8.2, 3.6, 2.5, 2.9, and 1.4, respectively, in CLL/SLL patients and 1.6, 3.2, 1.5, 1.3, 17.6, and 0.8, respectively, in NHL patients. When invasive melanoma was stratified by patient age and sex, the highest SIR (17.8) was found in men aged 0–49 years with CLL (P < 0.001).ConclusionsPatients with CLL/SLL or NHL have a higher risk for the subsequent development of rare skin cancers. Given the more aggressive nature of these malignancies in this setting, regular monitoring for the development and prompt treatment of cutaneous malignancy is prudent in patients with NHL and particularly in patients with CLL. Regular use of sun protection may decrease the morbidity associated with skin cancer in this immunosuppressed population.

Purpose To delineate outcomes of malignant melanoma (MM) and Merkel cell carcinoma (MCC) in patients with chronic lymphocytic leukemia (CLL) or non-Hodgkin's lymphoma (NHL). Patients and Methods We identified patients with MM or MCC reported to the Surveillance, Epidemiology, and End Results program and analyzed the effects of history of CLL/NHL on overall (OS) and cause-specific survival after MM or MCC. Expected survival was derived from patients with MM or MCC without CLL/NHL. Results From 1990 to 2006, 212,245 patients with MM and 3,613 patients with MCC were identified, of whom 1,246 with MM and 90 with MCC had a prior diagnosis of CLL/NHL. Patients with MM and a history of CLL/NHL had worse-than-expected OS as measured by standardized mortality ratio (SMR; SMR for CLL, 2.6; 95% CI, 2.3 to 3.0; SMR for NHL, 2.3; 95% CI, 2.1 to 2.6). MM cause-specific survival was worse than expected for patients with a history of CLL (SMR, 2.8; 95% CI, 2.2 to 3.4) or NHL (SMR, 2.1; 95% CI, 1.7 to 2.6). Among patients with MCC, OS was worse than expected for those with a history of CLL (SMR, 3.1; 95% CI, 2.2 to 4.3) or NHL (SMR, 1.9; 95% CI, 1.3 to 2.8). MCC cause-specific survival was worse than expected for patients with a history of CLL (SMR, 3.8; 95% CI, 2.5 to 5.9), but no difference was observed for NHL (SMR, 0.9; 95% CI, 0.4 to 2.1). Conclusion Patients with CLL before diagnosis of MM or MCC have significantly worse OS and MM or MCC cause-specific survival than those without a history of CLL/NHL.
