UNASSIGNED: Osteochondromas are the most common benign tumors of the bone and can be sessile or pedunculated. Although osteochondromas are typically seen in the long bones, they are rarely seen in the small bones of the hand or foot. Verruca vulgaris, also known as the common wart, is one of the most common skin conditions presenting to physicians and must be distinguished either clinically or histologically from other hyperkeratotic conditions, including bone conditions such as bone tumors that can place pressure on the skin and cause callus formation that can mimic a wart or create skin deformity. A high index of suspicion for underlying bone mass or tumor should be entertained when evaluating patients for skin conditions, particularly of the hand or foot, with failure to improve with treatment.
UNASSIGNED: This case report presents a 20-year-old male with a pedunculated osteochondroma of the left fourth distal phalanx with hyperkeratotic skin overlying the mass at the end of the toe. He was initially treated by a family doctor and podiatrist for verruca vulgaris for over 5 years with two treatments of liquid nitrogen cryotherapy and surgical excision of the mass when the treating podiatrist encountered bone and recommended radiographs. The family requested follow-up with our practice several days later after they were told the patient had a bone tumor. The patient requested surgical excision of the osteochondroma secondary to pain with activities and difficulties with his vocation as a pilot.
UNASSIGNED: All physicians must be mindful of an underlying bone tumor or mass in patients presenting with skin changes, particularly about the foot or hand. Knowledge that an underlying bone tumor can present as a verruca vulgaris may prevent a delay in diagnosis or unnecessary treatment when evaluating and treating a patient with a skin lesion. Fortunately, our case was a benign osteochondroma; a malignant tumor with a delay in diagnosis could lead to loss of limb or life.

BACKGROUND: Changes in the skin structure, including the collagen and elastin content, have been reported with massive weight loss (MWL) following bariatric metabolic surgery (BMS) and have been correlated to a higher risk of complications after body-contouring surgery (BCS). This study aimed at comparing the histological characteristics of the skin of patients having surgical MWL (SMWL) post-BMS to those with non-surgical massive weight loss (NSMWL).
METHODS: This prospective study compared the epidermal thickness, and collagen and elastin fibers content in 80 skin biopsies obtained from BCS procedures performed to patients who experienced MWL defined more than 50% of excess weight loss (%EWL) either SMWL (40 biopsies) or NSMWL (40 biopsies). Twenty biopsies in each group were obtained from abdominoplasties and 20 from breast reductions. Epidermal thickness was measured in H&E-stained sections, collagen fibers were assessed using Masson trichrome-stained sections, and elastin fibers were assessed using Modified Verhoeff\'s stained sections. Image analysis software was used to calculate the fractions of collagen and elastin fibers.
RESULTS: This study included 77 patients, 38 SMWL patients, and 39 NSMWL patients. The SMWL group had a significantly higher age (p < 0.001), a longer time interval from intervention (p < 0.001), higher initial weight (p < 0.001), higher initial BMI (p < 0.001), lower current weight (p = 0.005), lower current BMI (p < 0.001), and significantly higher %EWL than NSMWL group (p < 0.001). No significant differences were detected between the two groups regarding complications after abdominoplasty (p = 1.000). The elastic fibers content in the dermis was significantly higher in the abdominal region of the NSMWL group than SMWL (p = 0.029). All other parameters showed non-significant differences between NSMWL and SMWL in the skin of abdomen and breast.
CONCLUSIONS: The SMWL group had a significant reduction in elastic fiber content in the skin of the abdomen compared to the NSMWL group. The collagen content was equally reduced in both groups with non-significant differences in both breast and abdomen regions in both groups.

Polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma cell disorder, and skin changes (POEMS) syndrome is a multisystem disorder that has limited treatment options. Here, we described a case of a 55-year-old female subject who was treated for multiple drugs, but the skin symptoms continued to progress; the patient responded well to baricitinib. This suggests that JAK/STAT signaling pathways play an essential role in the pathological process of POEMS syndrome.

The progression of chronic venous disease (CVD) is characterized by edema of the legs and/or venous ulcers of the lower limbs in association with cutaneous signs and/or skin alterations, such as hyperpigmentation, corona phlebectatica, telangiectasia, eczematous dermatitis, lipodermatosclerosis, atrophie blanche, cellulitis, and induration. Xioglican cream is a galactosaminoglycan polysulfate and hyaluronic acid-containing medical device with strong hydrophilic, moisturizing, and soothing properties. This post-marketing observational study evaluated topical Xioglican cream in the amelioration of skin manifestations and clinical signs and symptoms in patients with CVD treated in routine clinical practice.
Adult patients (18-75 years) with a clinical diagnosis of C2-C3 CVD according to Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) classification who received 12 weeks of treatment with Xioglican (applied up to 3 times daily), according to investigator decision (and consistent with conventional clinical practice and established standard of care), were enrolled from two study sites in Italy. A range of endpoints were used to evaluate efficacy, safety, effect on patient quality of life (QoL), and patient satisfaction with topical application of Xioglican cream in the physiological restoration of skin signs and symptoms.
In patients with CVD (n = 30), Xioglican cream reduced CVD-related skin manifestations and associated symptoms, with significant reductions in leg circumference [mean ± standard deviation (SD): - 3.21 ± 3.39 cm for left and - 2.92 ± 2.70 cm for right legs, both p < 0.0001] and local edema (- 5.52 ± 7.94 cm, p = 0.0034) and significant improvement in Venous Clinical Severity Scores (mean 0.52 ± 1.94 decrease from baseline, p = 0.1952) observed after 12 weeks. Skin burning, pain, aching or tiredness, and QoL were also significantly improved. There was no change in CEAP classification. Globally, 92.0% of patients were \"Very satisfied\" or \"Satisfied\" with the product.
Topical treatment with Xioglican cream improves the signs, symptoms, and QoL of patients with CVD class C2-C3.

Patients experience many new and concerning symptoms during pregnancy and it is the role of the obstetric clinician to provide appropriate guidance, recommendations, and treatment options. Often times, these symptoms are related to hormonal and physiologic changes that occur and will resolve in the postpartum period. However, clinicians must be able to recognize more concerning pathologic symptoms that require further evaluation and treatment. This review provides updates on the evaluation and management of some of the common symptoms during pregnancy.

BACKGROUND: Lack of standardized imaging recommendations among mastectomy patients has led to variability in how recurrences are detected.
OBJECTIVE: To describe the findings and assess the diagnostic efficacy of ultrasound in the evaluation of symptomatic post-mastectomy patients.
METHODS: This single institution, retrospective study included 749 consecutive diagnostic chest wall ultrasound examinations performed in mastectomy patients, from January 2016 to June 2017. Chest wall ultrasound evaluated the mastectomy bed with or without reconstruction. Electronic health records were queried for the primary breast cancer histology prior to mastectomy, clinical symptoms prompting the diagnostic ultrasound, ultrasound findings, subsequent cytology and pathology, and follow-up data. Excluded were patients with a known recurrence, asymptomatic patients, and those with <2 years of clinical or imaging follow-up. Descriptive and comparative statistical analyses were performed.
RESULTS: Among the 749 ultrasounds performed, 58 malignancies were identified for a 7.7% (58/749) malignancy rate, with a median tumor size of 20 mm. Patients diagnosed with a malignancy most often presented with a palpable abnormality (79.3%, 46/58) or skin changes (13.8%, 8/58) and rarely with pain (1.7%, 1/58). Patients who underwent a biopsy yielding a benign result most often presented with a palpable abnormality (41.5%, 287/691), pain (25.6%,177/691), or postoperative swelling/suspected fluid collection (17.8%, 123/691). Diagnostic ultrasound yielded a 91.4% sensitivity (95% CI 81.0, 97.1), 96.1% specificity (95% CI 94.4, 97.4), 66.3% PPV3 (95% CI 57.4, 74.1), and 99.3% negative predictive value (95% CI 98.3, 99.7) for cancer detection. There were 5 false negative ultrasound cases after a skin punch biopsy was performed due to clinically suspicious skin changes.
CONCLUSIONS: Chest wall ultrasound has a high sensitivity and negative predictive value for detection of breast cancer recurrence in symptomatic patients after mastectomy. Skin changes remain an important clinical manifestation of a cancer recurrence.

Taiwan increased the Bacillus Calmette-Guerin (BCG) vaccination age from 24 h after birth to 5-8 months of age to lower BCG-related osteitis/osteomyelitis in 2016. However, the sequences of skin changes at the injection site and in the corresponding lymph nodes are unknown for infants vaccinated at an older age.
We prospectively collected the photographs of skin reactions within 6 months after vaccination. The type, size, onset time, and duration of the skin reactions were recorded and analyzed.
We enrolled 532 infants. The types and median times at onset of skin reactions were as follows: erythema at week 1, induration at week 3, ecchymosis at week 4, and ulceration at week 6. The peak skin responses were at week 6, with average sizes of 8.4 mm, 7.4 mm, and 8.2 mm for erythema, induration, and ecchymosis, respectively. The duration of induration was long, with 57.6 % and 23 % of the infants still having a response at week 12 and 24, respectively. The rate of induration size ≥ 20 mm was 1.7 % (95 % confidence interval: 0.8 %-3.2 %). Overall, 46.4 % of the infants experienced ulcerative change, with most occurring at week 6 (34.1 %), and 9.5 % and 4.1 % of the infants still had ulceration at week 12 and 16, respectively. Twelve infants (2.3 %) had spontaneous resolution of regional lymphadenitis, with the onset time ranging from week 1 to 12. All infants had developed a scar at the end of follow-up.
Our study demonstrates the typical appearance and time courses of skin reactions in infants who received the BCG vaccination at older than 5 months of age. Infants vaccinated at this age may have a more potent skin response with longer induration and ulceration than those vaccinated at birth.

Individuals infected with SARS-CoV-2 have been found to develop a variety of cutaneous symptoms. This study sought to describe varying cutaneous manifestations of COVID-19 in individuals presenting to an inpatient healthcare facility. We screened individuals who presented with COVID-19 for skin changes throughout the illness and administered a survey regarding demographics, medical history, and their cutaneous findings. Three individuals reported varying skin findings including wheals, petechiae, ecchymosis, and papules. One individual reported a worsening skin condition, psoriasis, as well as a new skin condition, seborrheic dermatitis. In conclusion, cutaneous manifestations of patients suffering from COVID-19 are wide-ranging and worsening skin conditions amongst these patients should be further investigated.

Polyneuropathy, organomegaly, endocrinopathy, M protein, skin changes (POEMS) syndrome is a rare multisystem paraneoplastic disorder. Here we describe a case of a 50 year old post-menopausal female who presented with chief complaints of difficulty in walking, getting up from squatting position and tingling sensation of bilateral lower limbs since 1 month. Additional unusual features in the patient included hepatosplenomegaly, endocrinal involvement in the form of hypothyroidism and elevated estradiol levels for her age. There were skin changes in the form of hyperpigmentation. M protein was not noted on serum electrophoresis but was visible on serum protein immunofixation (IgA lambda). She was investigated as a case of polyneuropathy and later a provisional clinical diagnosis of POEMS was made based on the presence of major and minor criteria. The patient was managed with methyl prednisolone, calcium carbonate and vit D3 and topical antibiotics for local infections.

Skin manifestations of systemic disorders give a clue to the organ involved and help identify the possible disease-causing injury. Skin changes of liver cirrhosis are not specific, as they may be seen in disorders not involving the liver. Thus, a constellation of skin changes along with systemic features may help us to identify the disease-causing liver cirrhosis. Pruritus is one of the most common and distressful symptoms of liver cirrhosis, severely affecting the quality of life, which further necessitates understanding cutaneous manifestations of cirrhosis. Other nonspecific cutaneous manifestations include spider telangiectasia, palmar erythema, paper money skin, xanthomas, pigmentation changes, nutritional deficiencies, hair changes, and nail changes. This review discusses the nonspecific skin manifestations associated with liver cirrhosis followed by specific cutaneous findings seen in common diseases causing liver cirrhosis, such as viral infections, biliary tract disorders, chronic alcoholism, and metabolic disorders. Early recognition of cutaneous features can help prevent or delay the development of complications and end-stage disease, decreasing morbidity and mortality.
