RESUMO
PURPOSE: Merkel cell carcinoma (MCC) is a rare neuroendocrine tumor of the skin, which mainly occurs in the sun exposed sites of white patients over 65 years, with a higher recurrence and metastasis rate. Clinically, MCC overlapping Bowen's disease (BD) is a very rare subtype of MCC. Few cases in the literature have been described and the management is not well defined. We summarize and update the epidemiology, clinical and histopathological features, metastasis characteristics, local recurrence rate and management of it by presenting two cases of MCC overlapping BD and reviewing the literature over the last 11 years. DESIGN: We consulted databases from PubMed, ResearchGate and Google Scholar by MeSh "Merkel cell carcinoma" and "Bowen's disease", "Bowen disease" or "squamous cell carcinoma in situ", from January 2013 to December 2023 and reviewed the literatures. We reported two additional cases. RESULTS: Total 13 cases of MCC overlapping BD were retrospectively analyzed, in whom mainly in elderly women over 70 years, the skin lesions were primarily located on the faces, followed by the extremities and trunk. Most of them were asymptomatic, firm, dark red nodules arising on rapidly growing red or dark brown patches, or presenting as isolated nodules. Dermoscopy evaluation was rarely performed in the pre-operative diagnostic setting. All cases were confirmed by histopathology and immunohistochemistry. The most definitive treatment was extended local excision, but local recurrences were common. Of the 13 cases, 4 cases experienced local or distant metastasis. One suffered from an in-transit recurrence of MCC on the ipsilateral leg after local excision and lymph node dissection, whose metastasis completely subsided after avelumab treatment and without recurrence or metastasis during 6 months of follow-up. CONCLUSIONS: MCC overlapping BD is a very rare skin tumor mainly predisposed on the faces, with high misdiagnosis rate and recurrence rate. Advanced disease at diagnosis is a poor prognostic factor, suggesting that earlier detection may improve outcome. The acronym, AEIOUN, has been proposed to aid in clinical identification. Our reports and the literature review can provide a better awareness and management of it.

BACKGROUND: The relationship between human papillomavirus (HPV) and Bowen disease (BD) is not fully understood. OBJECTIVES: To investigate the differences in HPV detection rates in BD samples across various body regions and analyse the expression patterns of p53, p16 and Ki-67 in relation to HPV presence. METHODS: Tissue samples from patients diagnosed with BD, confirmed through histopathology, were retrospectively collected. Next-generation sequencing was used for HPV DNA detection. Immunohistochemistry (IHC) for p16, p53 and Ki-67 was performed. RESULTS: Out of 109 patients with BD, 21 (19.3%) were HPV-positive. All identified types were α-HPVs, with HPV-16 being the most common. The HPV detection rate was significantly higher in the pelvic (9/13, 69%, P < 0.001) and digital (5/10, 50%, P = 0.02) areas compared with those in the other regions. HPV presence was significantly correlated with p53 negativity (P = 0.002), the p53 'non-overexpression' IHC pattern (P < 0.001) and p16-p53 immunostain pattern discordance (P < 0.001). Conversely, there was no notable association between HPV presence and p16 positivity, the p16 IHC pattern or Ki-67 expression. CONCLUSIONS: Our findings suggest the oncogenic role of sexually transmitted and genito-digitally transmitted α-HPVs in the pathogenesis of BD in pelvic and digital regions.

OBJECTIVE: By presenting a case study on multiple instances of Bowen's disease and the consistent use of narrow-band ultraviolet B (NB-UVB) phototherapy over a three-year period, our aim is to enhance the comprehension of domestic clinicians regarding the disease. Additionally, we seek to review existing literature, encouraging dermatologists to consider clinical secondary primary lesion diagnoses. METHOD: Our approach involves analyzing a diagnosed case of multiple Bowen's disease, examining clinical manifestations, histopathology, imaging results, and treatment methods related to NB-UVB phototherapy. We aim to facilitate discussion and understanding through a comprehensive literature analysis. RESULTS: An elderly male with a 30-year history of psoriasis vulgaris initiated continuous NB-UVB therapy three years ago. A year later, he developed red patches and plaques with distinct borders and scaly surfaces on his face, trunk, lower extremities, and scrotum. Histopathological examination confirmed Bowen's disease. Treatment involved liquid nitrogen cryotherapy, with no recurrence observed during the one-year follow-up. CONCLUSION: This case highlights that Bowen's disease, typically solitary, can manifest as multiple instances, especially in individuals with a history of psoriasis vulgaris. While NB-UVB stands as the primary treatment for psoriasis vulgaris, caution is warranted due to the potential risk of skin tumor induction with prolonged high-dose usage. Clinicians should be vigilant in monitoring and assessing the long-term implications of such therapies.

BACKGROUND: Non-melanoma skin cancer (NMSC), which includes both Bowen's disease (BD) and superficial basal cell carcinoma (sBCC), is the most commonly diagnosed cancer in Canada. BD and sBCC are amenable to minimally invasive treatments however, large-scale studies assessing long-term outcomes are lacking, particularly regarding the timing and duration of non-invasive combination treatments. OBJECTIVE: Examine the clinical cure rate of BD and sBCC using a combination treatment consisting of a single cycle of cryotherapy followed by a three to four-week course of topical 5-fluorouracil (5-FU). METHODS: Retrospective chart review at a single center. Inclusion criteria included histology-proven sBCC or BD treated with either a combination protocol, cryosurgery, or 5-FU alone. RESULTS: 310 biopsy-confirmed cases of BD and 176 biopsy-confirmed cases of sBCC were analyzed. Of these, 229 cases of BD and 61 cases of sBCC were treated with cryosurgery and immediate 5-FU application, yielding a clearance rate of 90% and 86.9% at 6 months from initial treatment. CONCLUSION: Cryosurgery followed by immediate 5-FU use may be an effective mode of treatment for BD and sBCC, negating the need for invasive procedures and allowing for increased accessibility. Further studies with longer follow-up intervals, comparisons with other non-invasive treatments, and evidence of histologic cure are required.

Actinic keratosis (AK) are common lesions in light-skinned individuals that can potentially progress to cutaneous squamous cell carcinoma (cSCC). Both conditions may be associated with significant morbidity and constitute a major disease burden, especially among the elderly. To establish an evidence-based framework for clinical decision making, the guideline "actinic keratosis and cutaneous squamous cell carcinoma" was updated and expanded by the topics cutaneous squamous cell carcinoma in situ (Bowen's disease) and actinic cheilitis. The guideline is aimed at dermatologists, general practitioners, ear nose and throat specialists, surgeons, oncologists, radiologists and radiation oncologists in hospitals and office-based settings, as well as other medical specialties, policy makers and insurance funds involved in the diagnosis and treatment of patients with AK and cSCC. A separate guideline exists for patients and their relatives. In this part, we will address aspects relating to epidemiology and etiology, diagnostics, surgical and systemic treatment of cutaneous squamous cell carcinoma (cSCC), surveillance and prevention.

Early cutaneous squamous cell carcinoma (cSCC) can be challenging to diagnose using clinical criteria as it could present similar to actinic keratosis (AK) or Bowen's disease (BD), precursors of cSCC. Currently, histopathological assessment of an invasive biopsy is the gold standard for diagnosis. A non-invasive diagnostic approach would reduce patient and health system burden. Therefore, this study used non-invasive sampling by tape-stripping coupled with data-independent acquisition mass spectrometry (DIA-MS) proteomics to profile the proteome of histopathologically diagnosed AK, BD and cSCC, as well as matched normal samples. Proteomic data were analysed to identify proteins and biological functions that are significantly different between lesions. Additionally, a support vector machine (SVM) machine learning algorithm was used to assess the usefulness of proteomic data for the early diagnosis of cSCC. A total of 696 proteins were identified across the samples studied. A machine learning model constructed using the proteomic data classified premalignant (AK + BD) and malignant (cSCC) lesions at 77.5% accuracy. Differential abundance analysis identified 144 and 21 protein groups that were significantly changed in the cSCC, and BD samples compared to the normal skin, respectively (adj. p < 0.05). Changes in pivotal carcinogenic pathways such as LXR/RXR activation, production of reactive oxygen species, and Hippo signalling were observed that may explain the progression of cSCC from premalignant lesions. In summary, this study demonstrates that DIA-MS analysis of tape-stripped samples can identify non-invasive protein biomarkers with the potential to be developed into a complementary diagnostic tool for early cSCC.

Bowenoid papulosis (BP) is a benign and possibly carcinogenic disease associated with human papillomavirus (HPV) infection, which has been increasingly recognised and paid attention to in recent years, but the potential mechanisms still remain unclear. In our study, three patients who were diagnosed with BP were enrolled into our research. Skin biopsies were taken and were separated into two parts, one part was for HE staining and the others were for RNA-sequencing (RNA-seq). All the three patents were human papillomavirus (HPV) positive and HE staining revealed typical skin histopathological changes in BP, including dyskeratosis, hyperplasia and hypertrophy of the granular and spinous layers, atypical keratinocytes. RNA-seq analysis demonstrated that a total of 486 differentially expressed genes (DEGs) were detected between the skin tissues from BP and the controls, among which, 320 genes were significantly upregulated and 166 genes were dramatically downregulated. GO enrichment revealed that antigen binding, cell cycle, immune response and keratinisation to be the most notably altered pathways, whereas KEGG analysis indicated that cell cycle cytokine-cytokine receptor interaction, ECM receptor interaction and p53 signalling pathway to be the most significantly changed signalling pathways in BP. Furthermore, metabolism-associated enrichment analysis showed that cholesterol metabolism, metabolism of xenobiotics by cytochrome p450 and pyrimidine metabolism to be the most dramatically dysregulated metabolic pathways in BP as compared to normal controls. Our study revealed that inflammation, metabolism and cell proliferation signalling pathways might be the most important pathways for BP disease, targeted inhibiting of these signals might be a potential method for BP treatment.

Paget's disease of the breast is a rare type of cancer that affects the skin of the nipple and usually the areola. At the same time, most patients also have one or more tumors in the immediate vicinity of the focus of mammary Paget's disease. This tumor must be distinguished from normal or atypical Toker cells, and also differentiated from diseases such as Bowen's disease of the nipple and melanocytic lesions of the nipple and areola region, including nipple melanoma and BAP1-inactivated nevus (Wiesner nevus). Currently, there is no routine pathological diagnostic algorithm for these conditions. The aim of the work is to formulate a clear clinical and morphological algorithm for diagnosing Paget's disease of the breast and Toker cells, Bowen's disease of the nipple and areola, as well as melanoma and BAP1-inactivated nevi of the above localizations. Surgical material obtained from patients with Paget's disease of the breast (18), Toker cells of the nipple (2), Bowen's disease of the nipple (6), melanoma of the nipple (1), BAP1-inactivated nevus (1) was studied. The material was examined histologically with hematoxylin and eosin staining, Alcian blue and PAS reaction, as well as immunohistochemically with the following panel of antibodies: CD138, p53, CK8, CK7, HER2/neu, EMA, HMB-45, Melan A, S-100, p63, p16 and BAP1. An easy-to-learn pathoanatomical algorithm for diagnosing Paget's cancer has been developed, which will be especially useful for pathologists who encounter pathology of the nipple and areola in their work.

Pagetoid Bowen disease is a subtype of Bowen disease that accounts for 5% of Bowen disease. It is extremely rare for Bowen disease to appear on the nipple-areola complex, with only seven cases described in the previous literature. Of those seven cases, only one was of the pagetoid subtype. We report two cases of pagetoid Bowen disease on this location, one of them being the first case of pagetoid Bowen disease affecting the nipple reported to date. On this location, it is crucial to perform a meticulous differential diagnosis to rule out Paget disease, because of its contrasting therapeutic and prognostic implications. In order to do this, clinical and histopathological aspects must be considered. From a clinical point of view, previous literature has stated that nipple involvement can be a clue that points to Paget disease. However, one of our cases shows that this is not always true. Regarding histopathological analysis, a complete excision of the tumor might be necessary to observe clear features of Bowen disease, such as full-thickness atypia of the epidermis and intercellular bridges. An immunohistochemical panel comprising carcinoembryonic antigen, gross cystic disease fluid protein, epithelial membrane antigen, p63, CK34betaE12, periodic acid-Schiff, estrogen receptor, and progesterone receptor can be decisive in complicated cases.
