There were few sounds more memorable than John Paul’s walking bass that lumbered along ominously like Lenny in Of Mice and Men,” Spitz writes about “Dazed And Confused.” In a pilot study of a new NGS-based test for melanocytic tumors, 16 benign nevi (including 7 spitzoid melanocytic lesions, 4 “epithelioid” nevi, 5 blue nevi variants) were compared against 15 melanomas ( 95). NGS findings in SN included BRAF, MET, NTRK1, and ROS fusions and for SM included EML4 fusion, BRAF, MAP2K1, and TERT mutations ( 95). Comparing FISH results against NGS for one SN and 3 SM cases, NGS concurred with positive FISH tests for 2 SM cases, showed malignancy in one FISH negative SM case, and was benign in one FISH positive SN case ( 95). In the same study, NGS was also able to correctly diagnose all malignant lesions ( 95). Thus, NGS may be able to mitigate the problem of false negatives, as we sometime see in FISH studies, and it may help to clarify the malignant potential of a melanocytic spitzoid lesion. Fluorescence in situ hybridization utilizes DNA probes labeled with fluorescent molecules to detect DNA sequences on metaphase chromosomes and/or interphase nuclei ( 90). With the identification of copy number gains and losses through aCGH, standardized FISH assay to assist in the diagnosis of melanoma have been developed and represent a viable assay to clarify the nature of problematic Spitz lesions ( 15, 90). The original standard melanoma FISH assay, currently still in use, test the following targets: CCND1 (11q13), RREB (6p25), MYB (6q23) and centromere 6 ( 15, 90). Efforts have been made to adapt this standard melanoma FISH panel to be more specific to spitzoid lesions. With the association of 9p21 homozygous deletions of CDKN2A with Spitz melanoma, a five probe assays (6p25, 8q24, 11q13, 9p21, CEN9) and a six probe assays (RREB1, CCND1, MYB, EP6, CDKN2A, and CEP9) have been developed ( 15, 80). FISH was found to be useful in stratifying risk in ASTs, with homozygous 9p21 deletions associated with significant aggressive behavior and intermediate risk of aggressive behavior in cases with 6p25 or 11q13 gains compared to FISH negative or 6q23 deletions ( 80, 91).

Spitz may not have had access to the three surviving Led Zeppelin band members, but his new interviews with associates including former Atlantic Records executive Phil Carson, Peter Grant’s former assistant Carole Brown, album cover designer Aubrey Powell and Plant’s PA Benji Le Fevre form a compelling narrative filled with recollections from people who were along for the ride as well. Interest in the utilization of artificial intelligence (AI) and machine learning to aid in clinical diagnoses of various medical conditions has exponentially grown in the past 20 years. Availability of improved training and advanced pattern-recognition algorithms and development of computer hardware capable of high-speed processing make the implementation of AI into the clinical setting more feasible ( 199). Within the field of dermatology and dermatopathology, applications of AI and machine learning include diagnosis of various lesions via AI recognition of clinical, dermatoscopic, and histopathology images ( 200– 202). Comparison of AI-diagnosed skin cancers with clinicians assessments has been shown to be comparable to the diagnostic skills of board-certified dermatologists ( 200, 203). Favors extremities, may be amelanotic or vascular, more common in females, median age 12y ( 106, 107) Some melanomas may display a small component of spitzoid features including granular pigmented or glassy eosinophilic cytoplasm ( 137). Other MMs may arise in or be associated with a conventional SN ( 137). As both types of tumors typically exhibit the same behavior as melanoma, defining these lesions as SM is not recommended ( 137).

Driver of lung cancer formation, can be treated with crizotinib, cabozantinib, and vandetanib ( 13) However, all of the quotes Spitz uses from the interview were previously published in Mark Blake’s excellent 2018 Grant biography “Bring It On Home,” itself a source for several other quotes used in Spitz’s book. A Me Too-era reassessment of Led Zeppelin’s off-stage behaviour Can be primarily epithelioid, primarily spindle cell, or combination of both; irregular nesting patterns; fascicular melanocyte nests in SM with ALK fusions; dermal rosette structures in SM with NRTK1 fusions; greater epithelioid predominance in SM with MAP3K8 fusions HRAS,” a proto-oncogene located on chromosome 11p, is the first genetic aberration that was associated with Spitz nevi ( 11, 111, 112). It is mutated (most often exons 2 or 3) in up to 15-20% of solitary Spitz nevi, but this number rises significantly in the presence of a chromosome 11p amplification (67%) ( 97, 99, 113). Mutations are widely varied but include 61Gln to Leu, 61Gln to Arg, and 12Gly to Arg ( 113). Additional genomic aberrations have been discovered and are relatively common, however, the significance of these aberrations is unknown ( 111). HRAS mutations have been shown on multiple occasions to aid in distinguishing Spitz nevus from Spitz melanoma, as HRAS is almost never present in melanoma ( 103). In a sample of over 150 melanomas, only one was found to have an amplification of HRAS ( 113). Because of this distinction, and due to a low rate of proliferation in these lesions, HRAS mutation is synonymous with a good clinical outcome ( 113). One exception to this is a study which found that amplified regions of acral melanomas (which have a poor prognosis) often contain HRAS mutations ( 114). All the right details I’d want in harsh conditions are there too: a protective hood that moves with your head, glove-friendly zipper tabs, ventilation options across the front and under the arms.

NGS was recently used to reclassify SN and SM from melanomas of Spitzoid features (MSF) after the WHO’s classification of skin tumors proposed elimination of lesions with BRAF and NRAS mutations from the categories of SN and SM ( 96). Out of 80 SN and 26 SM, 12 were reclassified as MSF based on the presence of BRAF and NRAS mutations detected by NGS and 81% of SN and 76% of SM post-reclassification displayed chimeric fusions and/or truncations ( 96). The majority of MSFs contained RAF, NRAS, NF1, and TERT promoter mutations and were associated with worse recurrence-free survival and metastatic potential than SN and SM ( 96). With the incorporation of genomic data being highly predictive of recurrence and the reclassification of lesions previously diagnosed as SN or SM through NGS, there is utility in using NGS to clarify diagnoses of SN and SM from MSF, with important implication for patient management ( 96). As mentioned above, though costs are declining, NGS is still significantly more expensive than aCGH and/or FISH studies and thus is not yet widely available ( 15).AST are more difficult to classify given that their characteristics overlap with SN and SM. Comparing dermoscopic features of 55 AST and 110 SN, AST are more likely to exhibit a multicomponent or non-specific pattern than SN, and exhibit a dotted vessel pattern at about the same frequency as SN ( 32). White lines were also predictive for AST, occurring in around 20% of AST ( 32). Shiny white lines are also a dermoscopic attribute of SM, highlighting the difficulty of distinguishing AST from SM ( 34). Initially, the prominent stromal sclerosis, decreased cellularity, and increased deposition of collagen characteristic of Desmoplastic Spitz Nevus were thought to be age-related change in the natural history of the SN ( 5, 143, 144). However, better characterization of these lesions have led to the contestation of its classification as either a subtype of Spitz tumor or as a separate entity ( 5, 6, 144– 146). The book’s chapter titles give an early indication of the scope of Spitz’s interest: “Just Boys Having Fun,” “Flying Too Close to the Sun,” “The Year of Living Dangerously,” and “Their Own Private Sodom and Gomorrah” are particularly telling examples.

One of the most commonly used markers, the Ki-67 protein (MIB-1), is expressed during the interphase and mitotic phases of the cell cycle (G1, G2, S, M) and is absent in the G0 phase, making it a useful marker to differentiate an actively proliferating melanoma from a quiescent melanocytic nevus ( 69). Compared with melanoma (where usually the ki67 proliferation index is >10% of melanocytes), SN tend to have a much lower Ki-67 proliferative index (<2% of melanocytes) and a lower dermal/epidermal count ratio (0.25 SN vs. 0.94 MM) ( 68, 73– 75). Within Spitz tumors, SN and AST share similar expression patterns of Ki67 in the superficial dermis or at the junction, without any expression usually at the base of the lesion; AST tend to display a higher proliferative index (2-10% of melanocytes) ( 68). SM tends to have a high and diffuse expression throughout the entire lesion and like other melanomas tends to display a higher proliferative index (>10% of melanocytes) ( 68). Loss or inactivation of CDKN2A on chromosome 9p is one of the most common molecular events in cutaneous melanoma, occurring in 50% of cases ( 79, 80). CDKN2A encodes the p16 protein, a cyclin-dependent kinase inhibitor that is vital to tumor suppression and whose absence promote cell cycle progression ( 80). SN stains strongly and diffusely for p16, but sometimes a mosaic pattern is also interpreted as a sign of benignity; on the contrary, complete absence or absence in sizable areas of the tumor, due to homozygous loss of 9p21, is an indication of loss of p16 expression and is a useful ancillary study to suspect melanoma ( 68, 81, 82). AST can present with either homozygous or heterozygous loss of 9p21 leading to some degree of variability in p16 positivity ( 80, 83). If you’re not sure, show the nail to your local pharmacist, who’ll be able to confirm that you’ve got a fungal infection and not some other less common nail problem. What should I look for in a fungal nail treatment? Robert Plant sings on “Ramble On” that “mine’s a tale that can’t be told,” but over the years many authors have attempted to tell the story of Led Zeppelin, with varying levels of success. In recent years, he appears to have relaxed this position, publishing an official photographic history of the band for its fiftieth anniversary in 2018 and co-operating with an authorised documentary film set to be released next year.It is a bit of a faff, but very powerful. First, you have to clean and soften the affected foot (or hand) in warm water, dry it, apply the ointment and cover it all with a plaster. You do this once a day. After the first 24 hours, you can start scraping at the infected nail tissue, which will start to come away. After a couple of weeks of this fun, you’ll have removed the entire infected nail. Plasters and a scraper are included in the box. Translocated Spitz nevi.

(C, D) Example of ROS fused Spitz nevus with a diffuse proliferation of melanocytes (C) mostly in small nests (D). Gl.inet's Spitz 4G router looks like many other routers in our guide, albeit smaller. It's not until you open it up and find the SIM card slot that you'd even know it was a 4G router. There's also a spot for a microSD card (up to 128 gigabytes) so you can use it as a media server if you like. The slot fits a micro SIM.
