We conducted a retrospective analysis on 148 adult patients with cutaneous BCC and SCC. Cases were divided according to the sub-types of BCC and the degree of SCC differentiation.

We did not find a significant association of the level of differentiation of SCC with the immunohistochemical expression for MMP-1 or COX-2. There was a significant association between BCC subtypes and immunohistochemical expression for MMP-1; positive expression of this enzyme reduces the odds for the infiltrative subtypes by 90%. A marginally significant association between BCC subtypes and immunohistochemical expression for COX-2 was also found. This enzyme was highly expressed in non-infiltrative basal cell carcinoma types (94%) compared with infiltrative types (71%). In conclusion, we did not find a significant predictor for SCC expression levels for either of two biomarkers, while the expression of MMP-1 in BCC was significantly inversely associated with the infiltrative type (moderate sensitivity and high specificity).

It is more frequent in adults, and early diagnosis is crucial since it has been reported to be associated with serious underlying systemic disorders, such as myeloproliferative diseases and severe manifestations like anaphylaxis (2,3). Treatment of MPCM depends on the presence of systemic involvement and/or the clinical symptoms of the disease itself. A 52-year-old woman was referred to us with pruritic brown red telangiectatic macules located on her arms, chest, and back (Figure 1, a, b, c) that had appeared over a period of 5 years. The patient also reported photosensitivity and facial flushing. Physical examination revealed a positive Darier sign (Figure 1, d) without other clinical signs suggestive of systemic involvement (e.g. lymphadenopathy, hepatosplenomegaly, malabsorption syndrome). Skin biopsy demonstrated abundant mast cells infiltration with granulomatic metachromasia (Giemsa stain; Figure 2, a) while immunohistochemistry demonstrated mast cells positivity in CD117/c-KIT (Figure 2, b). A detailed laboratory investigation was carried out, including complete blood count (IgE:1800 IU/mL), peripheral blood film examination, bone marrow biopsy, liver function tests, and serum tryptase levels (7 ng/mL). All performed tests were normal, thus excluding systemic disease. H1 receptor antagonists are considered the first-choice therapeutic option for control of symptoms among patients with skin mastocytosis (4,5). In our case, despite the standard application of an increased dose of different H1-receptor antagonists combined with topical steroid preparations, the patient showed no response to treatment and suffered a significant adverse influence on her quality of life and daily activities. Recent studies in single cases or small case-series have shown promising results for omalizumab in mastocytosis (6-8). Accordingly, our patient was switched to omalizumab 300 mg every 4 weeks for a one-year period. Both pruritus and flushing significantly improved after 2 months of treatment with only anti-IgE, and fully resolved during the fifth month of treatment. Almost 18 months, later the patient remains fully controlled with apparent significant improvement of her quality of life. The mechanisms of action for omalizumab in patients with mastocytosis are not well known. Omalizumab inhibits binding of IgE to the surface of mast cells and basophils by forming complexes with free IgE in serum, and this represents a possible explanation of the reduction of mast cell and basophil activation (9). In the future, omalizumab may be considered as a good alternative therapeutic option in cases where antihistamines have failed, though more research is necessary.</p>","PeriodicalId":50903,"journal":{"name":"Acta Dermatovenerologica Croatica","volume":"291 1","pages":"60-61"},"PeriodicalIF":0.6,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39382631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patient presented to our Department due to a fast-growing lesion on the proximal part of the nail unit. The lesion had appeared over several weeks, and it was extremely painful for the child. On the day of the 1st visit, the lesion was not bleeding but was very painful during examination and photo-documentation. Clinically, it presented as an exogenous tumoral lesion of the proximal 1/3 of the nail, partially exulcerated with one part exhibiting coagulated hemorrhage and with uneven coloration (Figure 1). The lesion was not sharply demarcated. Dermoscopically, the majority of the lesion presented an unspecific dermoscopic structure, orange background color, and matched the criteria for a vascular lesion: few unspecific vessels and hemorrhage. The \"sticky fiber\" sign was also present (Figure 2). Since the lesion was fast-growing and due to the unspecific dermoscopic appearance, the child was referred to a pediatric surgeon and a complete excisional biopsy of the lesion was performed.

Pyogenic granulomas of the nail unit are not a common finding, but our case confirms that even this location can be site of this type of benign lesion.

However, due to differential diagnosis that includes different types of tumors occurring at the nail unit, most importantly amelanotic melanoma and SCC, it is suggested to excise or take a biopsy of this type of lesion to be able to exclude aggressive tumor types, which are very rare but not impossible the in pediatric population (2).

The fight against this epidemic has become the center of our daily clinical practice as well as of our private lives, in which avoiding infection has become one of our most important goals. Even though COVID-19 is a potentially lethal disease, especially for the elderly and people with chronic diseases, it did not cause all the other life-threatening diseases to vanish. On the contrary, many scheduled medical activities and procedures, especially preventive and non-urgent internal and surgical activities, had to be postponed due to COVID-19 crisis. This interruption in the health care system can negatively affect the diagnosis and management of our patients with other health issues, namely malignant skin tumors, of which melanoma is the most aggressive. In this letter, we as dermatovenereologists from the Croatian Referral Centre of The Ministry of Health for Melanoma needed to express our concern regarding the increasing number of patients with delayed diagnosis of skin cancer, with special emphasis on melanoma detection and treatment. In the last few months, a large number of our newly-diagnosed patients with melanoma, as well as those with non-melanoma skin cancers, reported that they had noticed a suspicious skin lesion a few months ago but decided not to seek help from dermatologist due to the worrisome epidemiologic situation. In the current environment, clinical skin examination may be viewed as less important and thus postponed, but neglecting melanoma throughout the virus outbreak may lead to increased rates of morbidity, mortality, and consequently a greater financial burden for the health system (1). There are several reasons for such a relaxed attitude towards skin health in our patients. Unlike cardiac, pulmonary, or digestive difficulties, which patients consider life-threatening and for which they seek emergency care despite the coronavirus pandemic, skin tumors do not cause great subjective or significantly noticeable objective symptoms. Moreover, all of the skin tumors and especially melanoma , mostly present as small changes of just a few millimeters in diameter in the early stage at which they are prognostically most favorable. For the average person with no medical education, such small lesions usually do not cause any concern as they have no awareness of the fact that small and inconspicuous skin lesions may be dangerous and potentially even lethal. According to the recommendations concerning patient management during COVID-19 pandemic, oncological examinations should still be performed regularly (2). In spite of that, the cancelation of appointments, especially by patients who are being monitored for high-risk lesions, is inevitable when COVID-19 is disrupting everyone's lives.
